So do I. It may be something to do with this:
http://uk.php.net/strcmp
From the user notes...
When we make a comparison with == php automaticly converts strings to
integers when either side of the comparison is an integer, f.e.:
<?
$value = 0;
if($value == "submit") {
echo "Let's submit";
}
?>
Above would be succesful, since "submit" is converted to an integer (eq
0) and the equation is would return true; (that's why (1 == "1submit")
would also return true)
That's why we should use strcmp or === (checks type also), for string
comparisons.
