Question

I’m trying to create a .zip file from an asset from another server like so:

$url  = 'http://thindery.com/jsfiddle/butterfly.jpg';
$path = 'butterfly.zip'; 
$fp = fopen($path, 'w'); 
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp); 
$data = curl_exec($ch); 
curl_close($ch);
fclose($fp);

After I run the script I see the .zip on my server. When I download the .zip and try to open it on my Windows computer I get this error:

Windows cannot open the folder
The compressed (zipped) folder ‘butterfly.zip’ is invalid.

Anybody have an idea why it won’t open?

UPDATE

I understand my mistake here. I can see how my original code was just saving the .jpg as a .zip, instead of putting the .jpg in an archived (zipped) folder.

You really want to do this:

// if you have fopen wrappers forget about curl. way to complex for something simple
$jpg = file_get_contents('http://thindery.com/jsfiddle/butterfly.jpg');
$jpgName ='butterfly.jpg';

//use the built in zip functionality in php
$zip = new ZipArchive();
if ($zip->open("c:\temp\$jpgName.zip" , ZIPARCHIVE::CREATE)!==TRUE) {
    exit("cannot open c:\temp\$jpgName.zip\n");
}
$zip->addFromString($jpgName, $jpg);
$zip->close();
