Note that strpos() will return false if you supply an integer (thus, this presumably applies to
float, too) as needle. For example:
<?php
$id = 2; $text = '12345';
if(strpos($text, $id) === false){
echo 'Yes, is false';
}
?>
Will output 'Yes, is false', a behavior which may not be very intuitive (you'd think
it would be covered by PHP's type juggling feature).
This can be easily fixed by adding $id = (string)$id; above the strpos() statement.
