[SOLVED] Where can I get captcha script?

[shedokan]

Hello,

can you tell me where can I get a captcha script or a guide that will tell me how to create a captcha script without using font files.

because my server doesn't have FreeType support.

thanks.

PHPBB uses one, could probably use the same one.

here :  one captcha simplest file , try to change the variables to see what happens, save this as a php file, and in your html  use it for image source !

 

 

<?

// *** CAPTCHA image generation ***

// *** http://frikk.tk ***

 

session_start();

 

// *** Tell the browser what kind of file is come'n at 'em! ***

header("Content-Type: image/jpeg");

 

// *** Send a generated image to the browser ***

die(create_image());

 

// *** Function List ***

function create_image()

{

// *** Generate a passcode using md5

// (it will be all lowercase hex letters and numbers ***

$md5 = md5(rand(0,9999));

$pass = substr($md5, 10, 5);

 

// *** Set the session cookie so we know what the passcode is ***

$_SESSION["pass"] = $pass;

 

// *** Create the image resource ***

$image = ImageCreatetruecolor(100, 50);

 

// *** We are making two colors, white and black ***

$clr_white = ImageColorAllocate($image, 255, 255, 255);

$clr_black = ImageColorAllocate($image, 0, 0, 0);

 

// *** Make the background black ***

imagefill($image, 0, 0, $clr_black);

 

// *** Set the image height and width ***

imagefontheight(15);

imagefontwidth(15);

 

// *** Add the passcode in white to the image ***

imagestring($image, 5, 30, 3, $pass, $clr_white);

 

// *** Throw in some lines to trick those cheeky bots! ***

imageline($image, 5, 1, 50, 20, $clr_white);

imageline($image, 60, 1, 96, 20, $clr_white);

 

// *** Return the newly created image in jpeg format ***

return imagejpeg($image);

 

// *** Just in case... ***

imagedestroy($image);

}

?>

 

 

DO NOT FORGET TO start a session in your html form file .
