php is not omnipotent, because it can only catch exceptions, but not PHP-level errors.

If you want to capture PHP-level errors and handle them like exceptions, the method is as follows:

<code>
set_error_handler(function($errno, $errmsg) {
    var_dump($errno, $errmsg);
    // Any other Do
});
</code>

Error reporting attempt:

<code>$a = 1/0;
</code>

Obtained results:

<code>int(2) string(16) "Division by zero"
</code>
