Easy way to apply a function to an array

Question

I am aware of array_walk() and array_map(). However when using the former like so (on an old project) it failed

array_walk($_POST,          


        

Answer 1

I had trouble using the accepted answer as it caused me errors for reasons I couldn't work out. So for anyone having trouble with array_walk or array_map I found this to work.

foreach($_POST as $pk => $pv) $_POST[$pk] = mysql_real_escape_string($pv);
