equal
or in other words:

echo 'not equal';
equal
I would expect PHP to be evaluating string "444-44444" against integer "444"
(or string either way)
however, just for giggles, using === works...
php> if ($id === intval($id)) echo 'equal'; else echo 'not equal';
not equal
Using === will always fail because on the left you have a string and on
the right you have an integer which fails exact comparison based on
datatype mismatch.
When comparing a string to an integer using == PHP performs type
juggling and converts the string to an integer first.
