Corrupt image when extract from zip

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

Have you tried downloading the file via curl and unzipping it normally (i.e. without php)? To figure out whether the download causes the problem or the unzip.

You might also try to replace one of both parts using shell_exec (wget instead of curl, unzip instead of ZipArchive). I mean just for debugging, not for production maybe.
