Capcha

Mike wrote in another thread that this could replace a captcha

Code:

---

$texts = array("el301kfs","s94kf9ds","si340fsk","4iogfd0h","49ffle95","fo40fsl4","903mvlsmf");
$rand = rand(0,count($texts)-1);
header("Content-type: image/png");
$im = @imagecreate(80, 50)
  or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 255, 0, 0);
imagestring($im, 2, 6, 5, $texts[$rand], $text_color);
imagepng($im);
imagedestroy($im);

But how do I place this ? In a .php ?

create a file called captcha-image.php

That is a very basic CAPTCHA. It will present no trouble whatsoever to bots, and will stop blind people from accessing your site.

How can blind people access a computer anyway? Do they have special keyboards?

So I save the above code as capcha-image.php. Do I place <?- before it ?
And what code do I add in the form to see this .php file ?

Why would they need special keyboards? There's nothing to stop a blind person from typing, or even from learning to type (so long as some form of feedback is given telling them which key they're pressing).

Text-to-speech technologies help a lot.

Don't bother. As I said above, the above script might as well not be there, and will cause more problems than it will solve.

Another solutions, if I wish to place captcha ?

i think the basic problem there is that it uses only white and black.
