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;
}
