WordPress 3 Plugin Development Essentials

Testing PHP version

The following is how you test your what version of PHP looks like:

/**
* @param string    the minimum version of PHP required to run, e.g. '5.2.14'
*/
public static function php_version_gt($ver)
{
   $exit_msg = __("MyPlugin requires PHP $ver or newer. 
      Talk to your system administrator about upgrading");
      
   if ( version_compare( phpversion(), $ver, '<') ) 
   {
      self::$errors[] = $exit_msg;
   }
}

Again, you would add a corresponding function call to your loader.php file:

// Run Tests.
MyPlugin_tests::wp_version_gt('3.0.1');
MyPlugin_tests::php_version_gt('5.2.14');
