Question

I trying download a zip file using curl from one virtual host to another, in a same server. Zip file contains *.php and *.jpg files.

The problem is: sometimes JPG files get corrupt, like this:

Here is my code :

$out = fopen(ABSPATH.'/templates/default.zip','w+'); 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_FILE, $out); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_URL, 'http://share.example.com/templates/default.zip'); 
curl_exec($ch); 
curl_close($ch); 


$zip = new ZipArchive;
if ($zip->open(ABSPATH.'/templates/default.zip') === TRUE) 
{
    if($zip->extractTo(ABSPATH.'/templates'))
    {
        echo 'OK';
    }

    $zip->close();
} 

//$zip->close();

I don’t understand what happen to my jpg. I also tried using pclzip.lib.php, but no luck. How to solve this problem ?

Thanks in advance

Answer 1

Finally i found what is the problem.

I’m using Nginx web server, when i change nginx config files:

sendfile on;

became

sendfile off;

My image not corrupt anymore. So its not php or curl problem. Interesting article: http://technosophos.com/node/172
