captcha

Date: 2006-11-26 11:07PM

Removed member logins and placed a simpler captcha on forums to keep the spam down.

Code:

<?php //type 2 revision 3 Nov 27 2006

ini_set(\'session.gc_maxlifetime\',60*10); //10 minutes
$width = 140;

// make code
$codelen = rand(4,7);
$validchars = \"389ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghjkmnopqrstuvwxyz\";
$code = \"\";
for($i = 0; $i<$codelen; $i++)
{
  $code.=substr($validchars,rand(0,strlen($validchars)-1),1);
}
// save nc/lower hash in current session
$_SESSION[\'captcha\'] = md5(strtolower($code));
// create blank image
$image = imagecreatetruecolor($width, $height);
function random_color($image, $a,$b)
{
  return imagecolorallocate($image, rand($a,$b), rand($a,$b), rand($a,$b));
}
// colored sectional background
$R=0x00;
