Determining the version of PHP installed on a system is a common task for developers and system administrators. PHP is a widely-used server-side scripting language, and knowing its version is crucial for ensuring compatibility, troubleshooting issues, and maintaining a secure environment.
There are several methods to check the PHP version, each with its advantages and use cases. One common approach is to use the php -v command in the terminal or command prompt. This command displays the PHP version along with additional information such as the installation path and configuration settings.
