note 57150 added to function.uniqid

Based on this page, I wrote this and since it's what I was looking for in the first place, I thought I'd share it. It's my first bit of PHP code, so all feedback is very welcome: <?php class Guid { var $guidText; function Guid() { $s = strtoupper(md5(uniqid(rand(),true))); $this->$guidText = substr($s,0,8) . '-' . substr($s,8,4) . '-' . substr($s,12,4). '-' . substr($s,16,4). '-' . substr($s,20); } function toString() { return $this->$guidText; } function NewGuid() { $g = new Guid(); return $g->toString(); } } echo "New guid: " . Guid::NewGuid() . "\n"; ?> ---- Manual Page -- http://www.php.net/manual/en/function.uniqid.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57150 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57150&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57150&report=yes Search -- http://master.php.net/manage/user-notes.php
