Get user's name from Facebook Graph API

Question

I would like to know how is it possible to retrieve a string from an external page.

For example: In a PHP website, the user sends a facebook id, ex: 1157251270

Answer 1

Either you use :

$res_json = file_gets_contents("http://graph.facebook.com/1157251270")
$res = json_decode($res_json)

Or, if you prefer curl (here with https and access token) :

$ch4 = curl_init();
curl_setopt($ch4, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch4, CURLOPT_URL, "https://graph.facebook.com/1157251270?access_token=YOUR_ACCESS_TOKEN");
curl_setopt($ch4, CURLOPT_SSL_VERIFYPEER, false);

if(!$result = curl_exec($ch4))
{
    echo curl_error($ch4);
} else {
    $res = json_decode($res_json)
}

curl_close($ch4);
