Thanks so much. This came in handy with some cakePHP.

Great tip! Thanks a lot.

The only thing I notice is the + operator displays the opposite behaviour of array_merge. I need to put the keys in the first array are preserved.

So for the example:

$myArr = array_merge($array1, $array2);

I would use:

$myArr = array_merge($array2, $array1);

weird – I just ran into this same feature while doing some work on a ZF Route class. luckily the author of the base Route class I was using for inspiration had already used the + operator.
