Hi,

$_REQUEST values might as well contain arrays.

Consider this form:
<form action="test.php" Method="POST">
<input type="checkbox" name="bla[]" value="1">1<br>
<input type="checkbox" name="bla[]" value="2">2<br>
<input type="checkbox" name="bla[]" value="3">3<br>
</form>

When receiving $_POST["bla"] it contains an array.

The programmer wanted to make sure it is a string.

PS: I think you should avoid $_REQUEST. Just use $_POST and $_GET.
