Why cURL gives different output on server and localhost? - php

Question

The below code gives different output on localhost and server.
I tried changing useragents and browsers. Am I missing any header?
<?php
$headers[] = 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
$headers[] = 'Connection: Keep-Alive';
$headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8';
$headers[] = 'Accept-Language: en-us,en;q=0.5';
$headers[] = 'Accept-Encoding gzip,deflate';
$headers[] = 'Keep-Alive: 300';
$headers[] = 'Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7';
//$headers[] = 'Content-Length: 0';
$curl = curl_init();
curl_setopt($curl, CURLOPT_HEADERFUNCTION, 'dbg_curl_data');
curl_setopt($curl, CURLOPT_WRITEFUNCTION, 'dbg_curl_data');
curl_setopt($curl, CURLINFO_HEADER_OUT, true);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7');
//curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11');
curl_setopt($curl, CURLOPT_URL, "http://www.facebook.com/login.php");
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_ENCODING, 'gzip');
//curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
//curl_setopt($curl, CURLOPT_POST, true);
$html = curl_exec ($curl);
//curl_close ($curl);
echo '<fieldset><legend>request headers</legend>
<pre>', htmlspecialchars(curl_getinfo($curl, CURLINFO_HEADER_OUT)), '</pre>
</fieldset>';
echo '<fieldset><legend>response</legend>
<pre>', htmlspecialchars(dbg_curl_data(null)), '</pre>
</fieldset>';
echo '<fieldset><legend>$html</legend>
<pre>', htmlspecialchars($html), '</pre>
</fieldset>';
function dbg_curl_data($curl, $data=null) {
static $buffer = '';
if ( is_null($curl) ) {
$r = $buffer;
$buffer = '';
return $r;
}
else {
$buffer .= $data;
return strlen($data);
}
}
?>
Output on Localhost : http://pastebin.com/UbpTVc4f
Output on Server : http://pastebin.com/NURDksJy
I want output as its on localhost.

Why don't you start with something simple before you complicate your request as much as it is now and is hard to debug. For example, this code (run it in a separate file):
$curl = curl_init();
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7');
curl_setopt($curl, CURLOPT_URL, "http://www.facebook.com/login.php");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HEADER, 1);
$html = curl_exec ($curl);
print_r($html);
Should give you HTTP/1.1 302 Found in return.
