#2 Output a message about an outdated version of PHP
Suppose we have written a plugin that will run only on PHP v7 and above. Then we must provide that the main code of the plugin will not run if the version on the user's server is lower than required.
Suppose we use PHP 5.6.11 installed on the server, then:
if ( is_php_version_compatible( '7.0.0' ) ) { require_once __DIR__ . '/main-file-plugin.php'; } else { add_action( 'admin_notices', 'admin_php_version__error' ); } function admin_php_version__error() { ?> <div class="notice notice-error"> <p>You are using an old version of PHP. Ask your server administrator to update it! </div> <?php }
The code above is incomplete and only shows how the notification should work.
