note 21226 deleted from function.str-pad by cmb

Note Submitter: jared at dctkc dot com ---- matthew.somerville's code did NOT work for me. neither did bert@catsburg.com's. neither did any other documentation. (if I isolated the code by itself, they all worked; but in the context I was using it, $value was numeric, and there is NO WAY to force it to be a string in PHP). I had to roll my own. I used 'trim' to _force_ the value of $value to be string, because as long as PHP thought it was numeric, I could not use any form of left-padding with zeros. This worked (I use sprintf to left-pad $value with zeros to a length of 4): sprintf("%04s",trim($value));
