Check if class has method in PHP

Question

Currently my code looks like that:

switch ($_POST[\'operation\']) {
    case \'create\':
        $db_manager->create();
        break;
    case \'retrieve\':
         


        

Answer 1

You can use method_exists:

if (method_exists($db_manager, $_POST['operation'])){
  $db_manager->{$_POST['operation']}();
} else {
  echo 'error';
}

Though I strongly advise you don't go about programming this way...
