解决方案
这是我对SO的问题，我没有得到答案。但是，我现在有答案。这是你想要的完美的例子。我使用您的网站还包含的网页的源代码中的验证码来检索验证码。使用之间的（）从captcha-url提取该图像。然后保持会话并再次发送请求。部分是您必须将数据提交到表单的网址，而不是网页。

So bascially am new to php. I want to get catpcha from a website. Then I wanna show it on my webpage and send a small post request and get the results. The site I am talking about is http://www.bollywoodmotion.com/mobile-tracker-with-name.html
I want to get the captcha from that page to my page and to enter captcha in my page and send the same as from my page. I had done this in a software using c#. I also want a web version, since I have no idea on php. Any way I tried searching and got curl is the best option for me. So can some one help me with the sample php code.
This the request doing by it.

解决方案
This was my question on SO for which i didn't get answer.However, i have the answer now.This is the perfect example that you want. I retrieved the captcha using the captcha-url in the source code of the webpage which your site also contains. Extract that image from captcha-url using between(). Then maintain the session and send the request again.The imp. part is that you have to submit the data to the URL of the form, not the page.
<?php
$cookie="cookie.txt";
function open($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($ch, CURLOPT_COOKIEJAR,$cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE,$cookie);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch, CURLOPT_REFERER, $url);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
function between($string, $start, $end)
{
$out = explode($start, $string);
if(isset($out[1]))
{
$string = explode($end, $out[1]);
echo $string[0];
return $string[0];
}
return '';
}
function get_captcha()
{
$url = 'https://academics.vit.ac.in/student/stud_login.asp';
$open = open($url);
$code = between($open, '<img src='https://academics.vit.ac.in/student/captcha.asp', '">');
return 'https://academics.vit.ac.in/student/captcha.asp' . $code;
}
function rahul()
{
$capth=htmlspecialchars($_POST['code']);
echo $capth;
$username="xyz";
$password="abc";
$url=url of the form in which you want to submit your data;
$cookie="cookie.txt";
$veri=$capth;
$com="Login";
$postdata = "regno=".$username."&passwd=".$password."&vrfcd=".$veri."&submit=".$com;
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);

curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec ($ch);
echo $result;
$data = curl_exec($ch);
}
?>
