PHP Download Facebook User Image Profile Error - php

Question

help me to fix this problem
I want to download Facebook user image profile using PHP 5.3.27
I use this code, the image is downloaded but size 0 bytes and cannot be open.
first code:
function DownloadImage($url, $dest){
$curl = curl_init($url);
$fp = fopen($dest, 'wb');
curl_setopt($curl, CURLOPT_FILE, $fp);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_exec($curl);
curl_close($curl);
fclose($fp);
}
try{
$social_id='1234';
DownloadImage('http://graph.facebook.com/'.$social_id.'/picture', '../user_image/normal/'.$social_id.'.jpg');
DownloadImage('http://graph.facebook.com/'.$social_id.'/picture?width=141&height=141', '../user_image/bigger/'.$social_id.'.jpg');
}
catch(Exception $errr){
echo $errr;
}
and this is the second code..
with the same result (0 bytes of size and cannot be open)
$url = 'http://graph.facebook.com/1234/picture';
$img = '../user_image/bigger/1234.jpg';
file_put_contents($img, file_get_contents($url));

Answer 1

As I see
http://graph.facebook.com/1234/picture
do redirect to:
https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash2/t1.0-1/c47.7.85.85/s50x50/417599_10100236041078581_1583446385_a.jpg
Try to add:
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
TRUE to follow any "Location: " header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set).
So your code may looks like:
function DownloadImage($url, $dest){
$curl = curl_init($url);
$fp = fopen($dest, 'wb');
curl_setopt($curl, CURLOPT_FILE, $fp);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_exec($curl);
curl_close($curl);
fclose($fp);
}
try{
$social_id='1234';
DownloadImage('http://graph.facebook.com/'.$social_id.'/picture', '../user_image/normal/'.$social_id.'.jpg');
DownloadImage('http://graph.facebook.com/'.$social_id.'/picture?width=141&height=141', '../user_image/bigger/'.$social_id.'.jpg');
}
catch(Exception $errr){
echo $errr;
}
