note 29404 added to function.dechex

sherifgayed code above doesn't work when r,g or b are very small (for example rgb(11,6,2)), because HTML browser are expecting a six characters string after the # char. Use the following to add zeros in front smallest values : $htmlColor = str_pad(dechex($red),2,"0",STR_PAD_LEFT) $htmlColor .= str_pad(dechex($green),2,"0",STR_PAD_LEFT) $htmlColor .= str_pad(dechex($blue),2,"0",STR_PAD_LEFT) -- http://www.php.net/manual/en/function.dechex.php http://master.php.net/manage/user-notes.php?action=edit+29404 http://master.php.net/manage/user-notes.php?action=delete+29404 http://master.php.net/manage/user-notes.php?action=reject+29404
