Question

I’m creating some re-usable functions, and right now I have error handling setup like this:

<?php
...
public function insertAfter( $index, $objects )
{
    if ( ! is_int( $index ) ) {
        trigger_error( 'Cursor::insertAfter() expects parameter 1 to be integer, ' . gettype( $index ) . ' given', E_USER_WARNING );
    } else {
        // Do my regular code
    }

    return $this;
}
...

I tried setting it up to work just like PHP would handle an error. Is this an appropriate way to do things?

Answer 1

You may throws an exception. Take a look at Exception in PHP manual.

EDIT: Here are some useful SO threads.

1. PHP Error handling: die() Vs trigger_error() Vs throw Exception.
2. In PHP5, should I use Exceptions or trigger_error/set_error_handler?.
3. trigger_error vs. throwing exceptions
