Facebook profile image and download it to my web directory - php

Question

Take a Facebook profile image and download it to my directory "www.site.com/images"..
<?php $url = "https://graph.facebook.com/$id/picture?width=350&height=500&redirect=false"; ?>
The variable "$id" is taken from a textfield, I've tried getting around the "redirect" that facebook places on their images, so to get the "real url" I've decided to extract it from a JSON. In browser I receive this:
"url": "https://fbcdn-profile-a.akamaihd.net/hprofil[...]",
"width": 299,
"height": 426,
"is_silhouette": false
All I need is the "real url" to be extracted and saved unto my website's directory.
$.getJSON, seems to be the easiest way to separate the information.

Extracting/Separator script for JSON in PHP or JAVASCRIPT
Or Save "Image" to "Directory".

My solutions:
PHP with curl
<?php
$ch = curl_init("http://graph.facebook.com/$id/picture?width=350&height=500&redirect=false");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); // Mean 5 seconds
$content = curl_exec($ch);
$data = json_decode($content, true);
curl_close($ch);
var_dump($data["data"]["url"]);
PHP with file_get_contents()
<?php
$content = file_get_contents("http://graph.facebook.com/$id/picture?width=350&height=500&redirect=false");
$data = json_decode($content, true);
var_dump($data["data"]["url"]);
javascript with jQuery
var url = "http://graph.facebook.com/ID/picture?width=350&height=500&redirect=false";
$.get(url,function(resp) {
alert(resp.data.url);
});
EDIT
Have you tried to remove "&redirect=false"
"https://graph.facebook.com/$id/picture?width=350&height=500"
redirect to
"https://fbcdn-profile-a.akamaihd.net/hprofil[...]"
So you can do:
<?php
$url = "https://graph.facebook.com/$id/picture?width=350&height=500";
$data = file_get_contents($url);
$fp = fopen("img$id.jpg","wb");
if (!$fp) exit;
fwrite($fp, $data);
fclose($fp);

Answer 2

I used this code when storing images from fb.
$dir = "your_directory";
$img = md5(time()).'.jpg';
$url = "some_value";
$ch = curl_init($url);
$fp = fopen($_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.$dir.DIRECTORY_SEPARATOR.$img, 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);
