Display leading zeros in PHP

Question

I've created this column on my DB named trackingcode, it has the UNSIGNED ZEROFILL attribute so it would show the leading zeros in the DB. See below example.

Now I would send these tracking codes through email (PHP form to email). The problem is that on the email, it would only show the whole number but not the zero.

Is there a way to make the leading zeros show up in the email subject?

$email_subject = "PC Request # $newtracking";

Not sure if these values are stored as strings in your database, but either way you can fudge it with this

$val = substr("00" . $newtracking, -3);
