Introduction

Current PHP version knowing the version of PHP your website is running is essential for compatibility, security, and performance. PHP is a popular server-side scripting language commonly utilized in web development. Here’s a simple guide on how to check your PHP version.

What Is PHP?

Basic Concept: PHP stands for Hypertext Preprocessor. It’s a server-side scripting language used to create dynamic web pages.

Example:

If you’ve ever filled out a form online or logged into a website, PHP may have been involved in processing that information behind the scenes.

Why Check Your PHP Version?

1.Compatibility: Web applications and content management systems (CMS) such as WordPress, Joomla, and Drupal have specific PHP version requirements. For example, RazorHost customers running WordPress may need to ensure their PHP version meets the minimum requirement for the latest WordPress updates to function correctly.

2.Security: Older PHP versions might have unpatched security vulnerabilities. As new threats emerge, newer PHP versions include essential security updates and patches. For RazorHost users, running a supported PHP version is critical to maintaining site security and protecting against potential exploits that target outdated PHP versions.

3.Performance: PHP versions often come with performance enhancements. For instance, PHP 7 introduced significant speed improvements and reduced memory usage compared to PHP 5.6. RazorHost users can benefit from these performance gains by ensuring their server runs the latest PHP version. l

4.Access to New Features: Each PHP release includes new features and functionalities that can improve development processes. For example, PHP 8.0 brought advancements like the Just-In-Time (JIT) compiler and new syntax features. RazorHost customers can leverage these modern features by staying updated with the latest PHP versions, enabling more efficient and advanced coding practices.

How to Check Your PHP Version?

Using a PHP File

• Create a PHP File:

Launch your text editor and create a new file titled `phpinfo.php`.

Add the following code to the file:

php

Copy code

<?php

phpinfo();

?>

• Save the file.
• Upload the File:
  • Upload the `phpinfo.php` file to the root directory of your website using an FTP client or through your web hosting control panel.
• Access the File:
  • Open your web browser and navigate to http://yourdomain.com/phpinfo.php.
  • Look for the “PHP Version” section on the page.
• Example: Navigating to http://example.com/phpinfo.php will show detailed information about your PHP configuration, including the Current PHP version.

Using Command Line (For Advanced Users)

• Access Terminal:

If you have command-line access to your server (via SSH), you can check your Current PHP version by typing:

bash

• Output:
  • The terminal will display the Current PHP version along with other details.
  • Example: The output might be PHP 7.4.3 (cli) (built: Feb 26, 2020 15:43:09).

Using Web Hosting Control Panel

• Log In:
  • Access your web hosting control panel (e.g., cPanel, Plesk).
