Wierdness with arrays and string fns

[HarryF]

Wondering if I'm doing something wrong here.

One of the things I like about php is you can run a function on an array, and it will apply it to every element of the array e.g.

$_GET = myFunction ( $_GET ); 

That works marvellously most of the time but, certain functions turn every element of the array into the letter A, e.g.

$_GET = htmlspecialchars ( $_GET ); 

Will turn them all to an A (also found that nl2br, htmlentities, addslashes / stripslashes do the same).

Thankfully, str_replace works fine.

Anything I'm doing here or is the bug?

yeah.
there is a function for this
$_GET = array_walk($_GET , 'functionname');
that should fix your prob.

Thanks

Phew - many lines saved in writing my own functions.

your very lucky lol
I only found that function < 12 hours ago.
If you check out my post below you'll see why

you guys may also be interested in the array_map(), array_filter() and array_reduce() functions which are like the map, filter and reduce functions used in functional languages to work on lists... specifically array_map which is similar to array_walk
