PHP Version

If you want to check the PHP version of a script from within the script (printing that value in real time) you can use the phpversion() function like

$version = phpversion()

print($version)

However, for best practices it is advised to use the constant PHP_VERSION as there is no function call, and thus no function overhead — in many situations this will be the preferred method as it is cleaner and more economical.

$version = PHP_VERSION

print($version)

phpinfo() function

The phpinfo() function returns information about how PHP is specifically configured on that machine, if you need more detailed information than just the version. [2]
