[ask] how to get captcha with PHP cURL?

Hi all,

i'm doing my own project where this script fetch content from remote server, get captcha, display to user to fill in then submit it.

the problem is i can't get captcha for this site _http://abadijayaiklan.co.cc/pasang-iklan/ (remove underscore in front of url), its seems like their captcha using more complex session

btw this is my code, i've try it with other site and works perfectly, just can't get it work for site above.

<?php

function open($url)
{
	$ch = curl_init();
	
	curl_setopt($ch, CURLOPT_URL,$url);  
	curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2');
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_COOKIE, 1);
	curl_setopt($ch, CURLOPT_COOKIEJAR, "1");
	curl_setopt($ch, CURLOPT_COOKIEFILE, "1");
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);    
    $result = curl_exec($ch);  
    curl_close($ch);
	
	return $result;
}

function between($string, $start, $end)
{
	$out	= explode($start, $string);
	
	if(isset($out[1]))
	{
		$string	= explode($end, $out[1]);
		return $string[0];
	}
	
	return '';
}

function get_captcha()
{
	$url	= 'http://abadijayaiklan.co.cc/pasang-iklan/';
	
	$open	= open($url);
	
	$code	= between($open, '<img src="http://abadijayaiklan.co.cc/captcha.php', '">');
	
	return 'http://abadijayaiklan.co.cc/captcha.php' . $code;
}

?>

<form action="" method="post">
<img src="<?php echo get_captcha(); ?>" border="0" /><br />

Hi danx10, thanks for your reply,

anyway, your code and mine success to get URL of captcha, but still captcha can't load, bcause cookies was changed, or anything else.
i think we must save cookies temp and load captcha with cookies inside, but how?

thanks

 

 $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);  
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2');
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_COOKIE, 1);
    curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__)."/cookie.txt");
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_REFERER, 'http://abadijayaiklan.co.cc/pasang-iklan/');    
    $result = curl_exec($ch);  
    curl_close($ch);
    
    return $result;
