The first lines of any decent PHP quick script

bootstrap.php

<?php

declare(strict_types=1);

error_reporting(E_ALL);

set_error_handler(function ($severity, $message, $file, $line) {
    if ((error_reporting() & $severity) === 0)  {
        return false;
    }

    throw new ErrorException($message, 0, $severity, $file, $line);
});
