A helper class for WordPress plugins to check PHP version and other requirements.


  • PHP 5.6.0 or above
  • WordPress 5.2 or higher.


The best way to use this package is through Composer:

$ composer require mundschenk-at/check-wp-requirements

Basic Usage

  1. Create a \Mundschenk\WP_Requirements object and set the requirements in the constructor.
  2. Call the \Mundschenk\WP_Requirements::check() method and start your plugin normally if it returns true.
// Set up autoloader.
require_once __DIR__ . '/vendor/autoload.php';

 * Load the plugin after checking for the necessary PHP version.
 * It's necessary to do this here because main class relies on namespaces.
function run_your_plugin() {

	$requirements = new \Mundschenk\WP_Requirements( 'Your Plugin Name', __FILE__, 'your-textdomain', [
		'php'       => '5.6.0',
		'multibyte' => true,
		'utf-8'     => false,
	] );

	if ( $requirements->check() ) {
		// Autoload the rest of your classes.

		// Create and start the plugin.
