ขอคำแนะนำในการดึงข้อมูลจาก graph api โดยใช้ curl หน่อยครับ

$url = "https://graph.facebook.com/oauth/access_token?client_id=".$appid."&redirect_uri=".$url."&client_secret=".$app_secret."&code=".$code;
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $response = curl_exec($ch);
    curl_close($ch);
    
    $tmp1 = explode("&",$response);
    $tmp2 = explode("=",$tmp1[0]);

    $access_token = "";
    if(sizeof($tmp2)==2){
        $access_token = $tmp2[1];
    }

        $url = "https://graph.facebook.com/me?access_token=".$access_token;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        $response = curl_exec($ch);
        curl_close($ch);

        $profile = json_decode($response);
        print_r($profile);
