Captha Image Matching the Session Value.

[Stephen Alistoun <stephenalistoun@xxxxxxxxx>]

Hi all,

My captha code is working but the session code is not matching image
code(captha code).

How do i get them to match each other.


PHP CAPTHA
session_start(); 
	
	$fontArray = array('arial.tff' , 'impact.tff' , 'tahoma.tff' , 'tunga.tff'
, 'verdana.tff');
	
	$fontOne = md5(rand(0,50));
	$fontTwo = md5(rand(0,50));
	$fontThree = md5(rand(0,50));
	$fontFour = md5(rand(0,50));
	
	//Let's generate a totally random string using md5
	$md5_hashOne = md5(rand(0,999)); 
	$md5_hashTwo = md5(rand(0,999)); 
	$md5_hashThree = md5(rand(0,999)); 
	$md5_hashFour = md5(rand(0,999)); 
	//We don't need a 32 character long string so we trim it down to 5 
	$wordOne = substr($md5_hashOne, 15, 1); 
	$wordTwo = substr($md5_hashTwo, 15, 1);
	$wordThree = substr($md5_hashThree, 15, 1);
	$wordFour = substr($md5_hashFour, 15, 1);
	//Set the image width and height
	$width = 400;
	$height = 150; 
	//Create the image resource 
	$image = @imagecreatefromjpeg("CapthaBack.jpg"); 
	$grey  = imagecolorallocate($image, 255, 255, 255);
	
	imagettftext($image,20, rand(0,70), 30, 30, $grey , 'impact.ttf' ,
$wordOne);
	imagettftext($image,20, rand(0,70), 70, 30, $grey , 'impact.ttf' ,
$wordTwo);
	imagettftext($image,20, rand(0,70), 110, 30, $grey , 'impact.ttf' ,
$wordThree);
	imagettftext($image,20, rand(0,70), 150, 30, $grey , 'impact.ttf' ,
$wordFour);
	
	session_unset($_SESSION["security_code"]);
	
	$_SESSION["security_code"] = $wordOne . "" . $wordTwo . "" . $wordThree .
"" . $wordFour;
	
	header("Content-Type: image/jpeg"); 
	//Output the newly created image in jpeg format 
	ImageJpeg($image);
	//Free up resources
	ImageDestroy($image); 


HTML CODE
session_start(); 
<table>
<tr>					
									<td></td>
									<td colspan="2"><input type="text" name="captha" value=""><?php
echo "Test:    ".$_SESSION["security_code"] ?></td>
</table>

Thanks, 

Stephen
