PHP try-catch blocks: are they able to catch invalid arg types?

Question

Background: Suppose I have the following obviously-incorrect PHP:

    try{
        $vtest = \'\';
        print(array_pop($vtest));
    }cat         


        

Answer 1

A warning will always be produced by the code you provided but you can use set_error_handler to dictate how the warning is handled; i.e. you can cause it to throw an exception. Furthermore, you can use restore_error_handler to return to default error handling when your done.

function errorHandler($errno, $errstr, $errfile, $errline) {
    throw new Exception($errstr, $errno);
}
set_error_handler('errorHandler');
