For completeness one has to mention the possibility of using this function with PHP 5.3 closures:

$names = array("D\'Artagnan", "Aramis", "Portos");
array_walk($names, function(&$n) {
  $n = stripslashes($n);
};

The trap with array_walk being it doesn't return the array, instead it's modified by reference.
