I am aware of array_walk() and array_map(). However when using the former like so (on an old project) it failed
array_walk($_POST, 'mysql_real_escape_string');
Warning: mysql_real_escape_string() expects parameter 2 to be resource, string given.
So I went with this slightly more ugly version
foreach($_POST as $key => $value) {
$_POST[$key] = mysql_real_escape_string($value);
}
So why didn't the first way work? What is the best way to map values of an array to a function?
