In this article, we’ll try to draw a clear picture on which one of the two is better for a beginner by comparing the two on multiple factors.

Appearance (WordPress vs Blogger)

When it comes to appearance, both WordPress and Blogger offer a wide variety of pre-created themes that allow beginners to create visually appealing websites without worrying about the backend. However, WordPress has an edge in customization with ten times more themes and thousands of plugins, making it easier to tweak your website to your liking. So, in terms of appearance, WordPress is the clear winner.

Both WordPress and blogger offer a wide variety of choices when it comes to creating a visually appealing website. With multiple pre-created themes, both WordPress and blogger make it easier for a beginner to start blogging without worrying about the backend of their website. But coming to the modification, Blogspot does not provide many options but with WordPress, you can do all the tweaking you want to the website.

Writing (WordPress vs Blogger)

This is the most important aspect of the website for a blogger. It should be easy and convenient to post on your website. If it’s too complicated, then it will take a lot of time to update your blog which could create a hurdle to your blogging business.

So, when it comes to writing and posting blogpost is the simplest CMS. You only need to type your article on the BlogSpot, it is similar to typing in Microsoft word whereas it could get a bit complicated to post in WordPress. Blogspot is the clear winner when it comes to updating your blog.

Security (WordPress vs Blogger)

Blogger benefits from Google’s security systems, which are considered some of the best in the world. This means you won’t need to worry about security or hosting your blog. While WordPress is also secure, it has had some security holes in the past.

Support (WordPress vs Blogger)

The support system of the blogger is not as active as WordPress. There are very limited options for support. WordPress has an active support system. With their active community, you will get quick support from official sources. Also, there are entire forums dedicated to WordPress errors and problems which can help you fix your problems instantly. So, in terms of support for WordPress vs blogger, WordPress is again a clear winner.

Updates (WordPress vs Blogger)

Blogger is getting old and is not customizable enough for today’s need. It would be great to see some real updates and changes in the system but that has not happened. It almost seems like blogger is a side project for Google, which might even be compared to all the other services that Google offers.

WordPress is open-source software. There is no dependency on the company for regular updates. Which is why they get regular updates from developers and are quick to fix errors. So, in this round of WordPress vs blogger, WordPress wins.

In the end, WordPress seems like way ahead of the blogger when you compare the two. If the blogger remains the same you can expect it to die out. Already everyone has switched to WordPress and the remaining will soon. So, it would be better if you started out with WordPress. Hopefully, this article helped you choose the platform that is right for your need.

In conclusion, WordPress appears to be the better choice for beginners in 2026 when comparing WordPress vs Blogger. WordPress has an edge in customization, support, and updates, making it the more flexible and future-proof option. However, if you prioritize ease of use, Blogger may still be worth considering. We hope this comparison helps you make the best decision for your blogging needs.

Debugging is a crucial aspect of software development that enables developers to identify and correct errors in their code. In PHP, debugging can be a complex and challenging task, especially when dealing with complex applications. However, with the proper tools and techniques, it is possible to streamline the debugging process and quickly identify and resolve issues. In this article, we will explore some of the best methods for debugging PHP code.

Here, we are covering for best ways to debug in PHP:

1. 10 Proven Tips for Effective PHP Debugging
2. Mastering PHP Debugging: Best Practices and Tools
3. Streamline Your PHP Debugging Process with These Expert Tips

1. Utilize a PHP Debugger

The most effective way to debug PHP code is by using a PHP debugger. A PHP debugger is a software tool that allows you to test and debug PHP code interactively. It enables you to set breakpoints, step through code, and analyze variables and data structures to identify errors in your code. Popular PHP debuggers include Xdebug, Zend Debugger, and PHP Debug Bar.

<?php
// enable xdebug
xdebug_start_trace();

// define a function
function multiply($a, $b) {
  $result = $a * $b;
  return $result;
}

// call the function
$num1 = 5;
$num2 = 10;
$product = multiply($num1, $num2);

// stop xdebug trace
xdebug_stop_trace();

// print the product
echo "The product of $num1 and $num2 is $product.";
?>

2. Debugging with Error Reporting

PHP provides an error reporting system that can be beneficial in identifying errors and warnings in your code. By setting the error_reporting directive in your PHP configuration file, you can enable error reporting. For instance, you can set it to display all errors and warnings by adding the following line to your PHP code:

error_reporting(E_ALL);
ini_set('display_errors', 1);

This will display all errors and warnings on the screen, making it easier to identify and fix issues.

3. Use Log Files

PHP allows you to log errors and warnings to a file rather than displaying them on the screen. By setting the log_errors directive in your PHP configuration file, you can enable error logging. For example, you can set it to log errors and warnings to a file by adding the following lines to your PHP code:

ini_set('log_errors', 1); 
ini_set('error_log', '/path/to/error.log');

This will log errors and warnings to a file at the specified path, making it easier to track down issues.

4. Utilize Code Profilers

Code profilers are tools that aid in identifying performance bottlenecks in your code. They enable you to analyze the execution time and memory usage of your PHP code to pinpoint areas that can be optimized. So, Popular PHP profilers include Xdebug, Zend Performance Suite, and Blackfire.

5. Use Unit Tests

Basically, Unit testing is the practice of testing individual components of your code to ensure that they function as intended. By writing unit tests, you can ensure that your code is error-free and behaves as expected. You can use PHPUnit, a well-known PHP unit testing framework, to write and run unit tests.

6. Debugging with PHP IDEs

Most PHP integrated development environments (IDEs) provide built-in debugging support. For instance, PHPStorm has a built-in debugger that allows you to set breakpoints, step through code, and analyze variables and data structures to identify errors in your code.

WHY PHP IS GOOD CHOICE FOR WEB DEVELOPMENT

• Product Development

These days, to develop or create a website is a priority to your business on the internet. The designing and development are the two most promising steps which are crucial. PHP programming language is most widely used for website and web application development. It is a general-purpose, server-side scripting language that runs on a web server and is designed for making dynamic pages and applications.

As web development services options are secured, fast, and reliable which offers a lot more advantages to make it accessible to a lot of people. It is given a thought to what has made PHP programming language one of the most commonly used languages and is also a good choice for web development. Using PHP as its language has many advantages like it supports Oracle, Sybase, etc. It is used for creating simple functions, methods, and syntax. It also supports a database management system and another open-source database.

• Structure of PHP Language

People in this business need their website to be developed without any well-maintained structure. The PHP application maintenance like maintenance of any machine, website at every period of time needs to be updated. Selecting the best programming language is one that helps you to meet the requirements and develop the functionality which you need at a reasonable cost and within the decent expansion of maintainability and extensibility.

If you are new to the web development software environment and are just looking for a place to start, then PHP is not only a great choice but also it is still dominating the server-side web development with well over 50% of the market share. The PHP stands at 415,934 numbers in the top programming language usage distribution in the top 1 million sites, which means it is commonly used as 41.59% of the total languages. This language is capable to minimize code utilization and comes with its memory development function. To collect the object codes from outside is not common as far as the PHP based web application is concerned.

Below are some of the reasons that clearly explain why PHP programming language is the best choice for web development:

• Boost Simplicity

With PHP, coding is like writing an essay in English for a computer to read, except the essay is a piece of code that instructs it to create and run the website in the most efficient manner possible. To create a code in PHP is simple, and though you have rarely heard that some developers complain that this does not build the necessary coding habits in them.

• Works Exceptionally

The latest trends towards adaptive content have created CMS customization which is a crucial competitive need for the business. Adaptive content is content personalized for individual visitors to the website for creating a one-to-one experience for the visitors. This is only possible if the website’s code can be customized and integrated with the help of CMS.

• Increased Programming Talent

This programming language is often used to create a large pool of talent to choose from for modifications and building and lowering the cost per hour for those services. To update your site in the future, it would be a better choice to select and hiring staff a member for the task or work with an alternate provider than the one who built your site.

• Embed-ability

The recent trend in adaptive content has made the responsive website and fluid grid systems even more pertinent for organizations. HTML5 is the unquestioned industry to develop a highly dynamic and responsive website. This is where PHP surfaces as the language which allows its code to be easily embedded into HTML language.

• Standard library

The extent of its standard library only makes the differentiation between the good programming languages from a great one. Libraries play an important role to simplify and speeding the data processing ability of the language. It offers extensive support for HTTP fetching, regular expressions, URL parsing, and database drivers. It is completely true that the library is incoherent, but the community’s on it.

Performance

Nowadays, most of the users abandon the website which takes more than 3 seconds to load. Hence, the developers have to explore ways to keep the visitors engaged by gaining the website loading speed. It comes with JIT (Just in Time) engine which compiles the PHP code into machine language for better engaging results.

What is Wayback Machine?

The Wayback Machine is a digital archive of the World Wide Web, founded by the Internet Archive, a nonprofit library based in San Francisco. It allows the user to go “back in time” and see what websites looked like in the past.

Wayback Machine(www.archive.org) is the best tool to recover/access old, deleted website pages. It’s part of a non-profit organization that tries to have a duplicate backup of all the websites on the Internet.

It has saved over 435 billion Web pages, which probably isn’t all the content on the Internet.

Steps to access old, deleted web pages on Internet are here:

• Open website of Wayback Machine i.e. www.archive.org.
• Enter the URL of the website that you want to access in the search box on the top of the website.
• Hit Browse History Button.
• You’ll prompt a calendar view. Select the year, month, and date.
• That’s all! Now you’ll see the old, deleted page on your screen.

Another way to get a few days back data of your website or webpages is Search Engine Cache

If you’re looking for a page that was deleted recently, then it might be easier to find it through a search engine such as Google, Yahoo, or Bing. As long as you’re able to find the webpage in a search engine, you should be able to load a backed-up copy of the page as well. This is how it works:

1. Open the search engine you like. Google’s caching is very good, so we suggest you use it.
2. Paste the link of the missing webpage in the search bar if you know it, or just search for the page to find the link you need.
3. Under the blue text of the link, you’ll see a line of green text, which is the URL of the webpage. Click the down arrow next to the green URL text.
4. Click Cached. This will show you a saved version of the page you wanted, along with details of when the backup was made.
5. If this page does not load properly, you can try clicking the Text-only version on the top right side. This will lose all images that were on the page, but if it isn’t loading correctly, this will still let you get to the important data you needed.

Summary for How to Download old deleted websites in 2024

As I have told you two ways to get your old data or webpages. WayBack Machine can provide you more than 1,2 or 5-year-old data but search engine cache can only provide a few days back data. So, It’s on your requirement how you need to use this.

The solution for “WordPress asking for FTP credentials to install a plugin or delete a plugin” is:

step1: you need to the WordPress home directory and find the wp-config.php file.

Step2: Open the wp-config.php file add define('FS_METHOD', 'direct' );. After adding this line and now save the file and check again by installing plugins.

why use FS_METHOD = 'direct'?

Unfortunately, WordPress’s logic for detecting an at-risk environment is flawed and produces both false-positives and false-negatives. Whoops. The test involves creating a file and making sure it belongs to the same owner as of the directory it lives in. The assumption is that if the users are the same, PHP is running as your own account and it’s safe to install plugins as that account. If they’re different, WordPress assumes that PHP is running as a shared account and it’s not safe to install plugins as that account. Unfortunately, both of these assumptions are educated guesses that will frequently be wrong.

You would use define('FS_METHOD', 'direct' ); in a false positive scenario such as this one: you are part of a trusted team whose members all upload files through their own account. PHP runs as its own separate user. WordPress will assume that this is an at-risk environment and will not default to ‘direct’ mode. In reality, it’s only shared with users you trust, and as such 'direct' mode is safe. In this case, you should use define(‘FS_METHOD’, ‘direct’) to force WordPress to write files directly.

What’s the risk?

On a poorly configured shared host, every customer’s PHP will execute as the same user (let’s say apache for discussion). This setup is surprisingly common.

If you’re on such a host and use WordPress to install the plugin using direct file access, all of your plugin files will belong to apache. A legitimate user on the same server would be able to attack you by writing a PHP script that injects evil code into your plugin files. They upload their script to their own website and request its URL. Your code is successfully compromised because their script runs as apache, the same one that owns your plugin files.

Updating WordPress is just a 20-second task and it takes me 3 days. so, finally, after so much research I got my solution and now I will share it with you.

Diagnosing the “Installation Failed: Could Not Create Directory.” Error in WordPress (2 Methods)

The good news about this error is that it’s relatively easy to fix. Most of the time, correcting your permissions will clear everything right up. Before you start work on that solution, however, you may want to make sure that it can actually solve your problem.

Below, we’ve outlined two methods for determining whether your site is experiencing a permissions-related error.

1. Use the WordPress Site Health Tool
2. Check Your Server’s Error Log

So let’s discuss why this issue (Unable to Update WordPress) comes?

As I observed the issue very deeply and I found a few main issues are given  below:

1. WordPress files or directory is missing. You can download WordPress manually and add the missing file or replace the whole directory.
2. WordPress files or directory permission should not be as per guidelines. you can download WP Security Plugin and go to the file system security page to check files and directory permissions.

   

3. if you tried both methods given above then definitely you are using Dedicated Linux Server (Redhat, Centos, or any other). So in this case you need to update your directory user and its group. sudo chown -R apache:apache /path/to/WordPress.

This command will help you. for Linux servers, you can use this command as given below.

sudo chown -R apache:apache /var/www/html/WordPress

Here, the WordPress means your directory if your WordPress is in the main directory then remove the “WordPress” word from the end. this will update your user and group from root to apache. after this command, you can check file and directory status by ls -l  command.

after this command now you can try again to update WordPress from your admin panel. if you again failed that means you have an issue as I had.

Errors on your WordPress site can slow down your work and create serious inconveniences for both you and your users. For instance, the “Installation failed: Could not create directory” message can prevent you from providing a key feature or functionality.

Now Please follow my steps very carefully and I am expecting that you tried all ways given above. So, Here you need to only 2 last commands for this problem.

The final way to solve this issue “Unable to Update WordPress”:

Let’s get started! just enter the command given below to check your files. It’s again the “Ls” (Listing) command.

ls -Z /var/www/html/path_to_your_website_folder/

After this command, you will get the result given below. if you saw the same something is this. that means your user and group is apache: apache.

Now step 2  is run the command again given below:

chcon -R --type httpd_sys_rw_content_t /var/www/html/rr/path_to_your_website_folder/

So, After this command, your WordPress will upgrade to the latest version. I hope my blog will be helpful to you. Please share this on social media so it will rank high for others. You can also read about, How to earn money with any investment. and Top freelancing languages.

if ( 'your-name' == $tag->name ) {
 $your_name = isset( $_POST['your-name'] ) ? trim( $_POST['your-name'] ) : '';

if (preg_match('/[0-9]/', $your_name)) {
  $result->invalidate( $tag, "The field contains numeric." );

    $your_job = isset( $_POST['your-job'] ) ? trim( $_POST['your-job'] ) : '';

    $result->invalidate( $tag, "The field contains numeric." );
   }
  }
 return $result;
}

add_filter( 'wpcf7_validate_email*', 'custom_email_validation_filter', 50, 2 );

function custom_email_validation_filter( $result, $tag ) {
 if ( 'your-email' == $tag->name ) {
 $your_email = isset( $_POST['your-email'] ) ? trim( $_POST['your-email'] ) : '';

 global $wpdb; 
 $cf7table = $wpdb->prefix.'db7_forms';

  $db = $wpdb->get_results ( "SELECT * FROM $cf7table WHERE `form_value` LIKE '%".$your_email."%' "); 
  //echo $wpdb->num_rows;
