actually the logic is follow:
every array has a key, therefore, you use:
foreach($variables as $key => $value) {
$variables[$key] = strip_tags($value);
$variables[$key] = AddSlashes($value);
}
where you get an array element with whatever key it uses, work on it's value
and assign it back with the original key, overriding it in other words.

Subject: [PHP] foreach loop
When I go through a foreach loop, are the values of the individual items in
the array changed?
For instance:
$variables = array($author_firstname, $author_lastname, $author_dob,
$author_dod, $author_bio);
foreach($variables as $value) {
$value = strip_tags($value);
$value =
AddSlashes($value);
}
will the values be changed outside of the loop?
