Facebook页面抓取

我试图废弃一个facebook页面(https://www.facebook.com/pages/PTSD/455847705426)我找到了这个脚本登录到facebook。

<?php
$EMAIL = "me@mail.com";
$PASSWORD = "facebookPassword";
function cURL($url, $header=NULL, $cookie=NULL, $p=NULL)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, $header);
curl_setopt($ch, CURLOPT_NOBODY, $header);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
if ($p) {
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $p);
}
$result = curl_exec($ch);
if ($result) {
return $result;
} else {
return curl_error($ch);
}
curl_close($ch);
}
$a = cURL("https://login.facebook.com/login.php?login_attempt=1",true,null,"email=$EMAIL&pass=$PASSWORD");
preg_match('%Set-Cookie: ([^;]+);%',$a,$b);
$c = cURL("https://login.facebook.com/login.php?login_attempt=1",true,$b[1],"email=$EMAIL&pass=$PASSWORD");
preg_match_all('%Set-Cookie: ([^;]+);%',$c,$d);
for($i=0;$i<count($d[0]);$i++)
$cookie.=$d[1][$i].";";
/*
NOW TO JUST OPEN ANOTHER URL EDIT THE FIRST ARGUMENT OF THE FOLLOWING FUNCTION.
TO SEND SOME DATA EDIT THE LAST ARGUMENT.
*/
$page_html =  cURL("https://www.facebook.com/pages/PTSD/455847705426",null,$cookie,null);

?>

变量$page_html现在只有几个帖子，而且他们在非常复杂的代码我的问题是

1. 如何获取所有帖子。
2. 是否有其他方法可以返回给我完整和清晰的数据?
3. 是有一些方法有json格式的所有帖子。

请告诉我关于这方面是否有一些有用的教程或文章。
