    To check the version of PHP installed on your system, there are several methods you can use:

    1. Using the Command Line:

      • If you have access to the command line (also known as the terminal in Linux/Mac or Command Prompt in Windows), you can simply type the following command:
        php -v
        
      • This command will display the PHP version installed on your system, along with some additional information.
    2. Using a PHP Script:

      • You can create a small PHP script that calls the phpversion() function, which returns the current PHP version. Here's an example of what that script might look like:
        <?php
        echo 'PHP version: ' . phpversion();
        ?>
        
      • You can run this script on your web server, and it will display the PHP version in your web browser.
    3. Checking in Web Hosting Control Panel:

      • If you're using a web hosting service, most control panels (like cPanel, Plesk, etc.) will display the current PHP version. You can usually find this information in the "PHP Settings," "Software" section, or something similarly named.
    4. Using phpinfo() Function:

      • Another method is to use the phpinfo() function, which provides a comprehensive overview of your PHP environment, including the version. Create a PHP file with the following code:
        <?php
        phpinfo();
        ?>
        
      • Run this file on your server, and it will display a lot of information about your PHP setup, including the version. Be cautious with this method, as phpinfo() reveals a lot of information about your server, which could be a security risk if publicly accessible.
    5. Check Package Manager (Linux Systems):

      • On Linux systems, you can also check the PHP version through the package manager. For instance, on Debian-based systems like Ubuntu, you can use:
        apt list --installed | grep php
        
      • This command lists all installed packages related to PHP, including the version.

    These are the common methods to check the PHP version. The best method depends on your specific setup and whether you have command line access or are running PHP through a web server.
