note 108599 added to function.unpack

I wrote a quick pair of functions using pack/unpack for converting between raw binary (e.g. openssl_random_pseudo_bytes() output) and hexadecimal (e.g. hash() output): <?php function raw2hex($raw) { $m = unpack('H*', $raw); return $m[1]; } function hex2raw($hex) { return pack('H*', $hex); } ?> Feel free to suggest any improvements, but I thought this was worth sharing. ---- Server IP: 69.147.83.197 Probable Submitter: 132.170.82.64 ---- Manual Page -- http://www.php.net/manual/en/function.unpack.php Edit -- https://master.php.net/note/edit/108599 Del: integrated -- https://master.php.net/note/delete/108599/integrated Del: useless -- https://master.php.net/note/delete/108599/useless Del: bad code -- https://master.php.net/note/delete/108599/bad+code Del: spam -- https://master.php.net/note/delete/108599/spam Del: non-english -- https://master.php.net/note/delete/108599/non-english Del: in docs -- https://master.php.net/note/delete/108599/in+docs Del: other reasons-- https://master.php.net/note/delete/108599 Reject -- https://master.php.net/note/reject/108599 Search -- https://master.php.net/manage/user-notes.php
