  First: Most php functions always return a modified version of the
  variable instead of modifying them directly. So in order to
  actually keep the changes:
  
    $value = stripslashes($value);


  Second: 
  If you are using php 5 you can do something like, note the way
  $value is referenced with &:

    foreach($array as &$value) {
      $value = stripslashes($value);
    }


  php 4's foreach always works on a copy so you have to access the
  array directly:

    foreach($array as $index => $value) {
      $array[$index] = $value;
    }
