note 57821 added to function.uniqid

Concerning the previous user's class: I'm not sure what you were attempting, but your overall usage of the class has some syntax errors and concept misapplications. For example, the NewGuid method is wrong and not needed. Instead, try: <?php class Guid { var $guidText; function Guid() { $this->guidText = md5(uniqid(rand(),true)); return $this->guidText; } function toString($separator = '', $case = false) { $str =& $this->guidText; if ($case) { switch ($case) { case 'uc': $str = strtoupper($str); break; case 'lc': $str = strtolower($str); break; default: $str = $str; } } $str = substr($str,0,8) . $separator . substr($str,8,4) . $separator . substr($str,12,4). $separator . substr($str,16,4). $separator . substr($str,20); return htmlspecialchars($str); } // do some other stuff } $obj = new Guid(); echo 'Dash: ' . $obj->toString('-'); echo 'Lower-case with "?" as separator: ' . $obj->toString('?', 'lc'); ?> This method just gives a bit more options, so if you want different methods to do different things or whatever. ---- Manual Page -- http://www.php.net/manual/en/function.uniqid.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57821 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57821&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57821&report=yes Search -- http://master.php.net/manage/user-notes.php
