I want to read an external site after submit code with captcha. But using (PHP) file_get_contents the captcha is loaded 2 times, so its wrong.
The Form load an image to solve the captcha and sent via POST to the original site that show the result. Normally I solve the captcha and than, in the new site, I read (with my eyes) the content.
Now I want to let PHP read the content. I always solve first the captcha (in my page) and than send it to the other site and let (php) "file_get_contents" read the content.
HERE MY CODE..
<?php
$captcha = $_POST["captcha"];
?>
<html>
<form method="post" action="(this page)">
<img src="remote-captcha"><input type="text" name="captcha">
<submit>
<?php
$postdata = http_build_query(
array(
'captcha' => $captcha
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('https://www.form-page', false, $context);
$search = '/<div class="myclass">(.*)<\/div>/';
preg_match($search, $result, $show);
echo $show[0];
?>
At this point the form is loaded 2 times so the captcha is wrong.
Can someone help me?
