note 53529 added to function.hexdec

Bullet-proof hex-to-rgb colour converter like brian at sagesport dot com wanted, just far fewer code lines. As a bonus, gives you the ability to return as string or array: <?php function &hex2rgb($hex, $asString = true) { // strip off any leading # if (0 === strpos($hex, '#')) { $hex = substr($hex, 1); } else if (0 === strpos($hex, '&H')) { $hex = substr($hex, 2); } // break into hex 3-tuple $cutpoint = ceil(strlen($hex) / 2)-1; $rgb = explode(':', wordwrap($hex, $cutpoint, ':', $cutpoint), 3); // convert each tuple to decimal $rgb[0] = (isset($rgb[0]) ? hexdec($rgb[0]) : 0); $rgb[1] = (isset($rgb[1]) ? hexdec($rgb[1]) : 0); $rgb[2] = (isset($rgb[2]) ? hexdec($rgb[2]) : 0); return ($asString ? "{$rgb[0]} {$rgb[1]} {$rgb[2]}" : $rgb); } ?> Handles 2, 3, and 6 character colour codes with leading # or &H. ---- Manual Page -- http://www.php.net/manual/en/function.hexdec.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53529 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53529&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53529&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53529&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53529&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53529&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53529&report=yes Search -- http://master.php.net/manage/user-notes.php
