The method of obtaining the PHP version depends on the operating system and server setup. Here are some common methods:
Command Line Interface (CLI): The PHP version can be checked using the command "php -v" on the command line.
phpinfo() function: This function retrieves information about the PHP configuration, including the version. To use it, create a PHP file with the following code:
Server Control Panel: Many web hosting companies provide control panels that show the PHP version installed on the server.
Web-based tools: Some online tools can detect the PHP version of a website, such as WhatIsMyPHP.com or Sucuri SiteCheck.
