Note: Only the first 65535 entries will be returned, even if your archive contains more entries. See https://bugs.php.net/bug.php?id=59118 for details.

zip_read — Read next entry in a ZIP file archive
Reads the next entry in a zip file archive.
A ZIP file previously opened with zip_open().
Returns a directory entry resource for later use with the
zip_entry_... functions, or
there are no more entries to read, or an error code if an error
If you get an error like this:
Warning: zip_read() expects parameter 1 to be resource, integer given in xxxxxx on line x
It's because zip_open() failed to open the file and returned an error code instead of a resource. It took me a while to figure out why it failed to open the file, until I tried to use the FULL path to the file.
// Even if the file exists, zip_open() will return an error code.
$file = 'file.zip';
$zip = zip_open($file);
// The workaround:
$file = getcwd() . '/file.zip';
$file = 'C:\\path\\to\\file.zip';
This worked for me on Windows at least. I'm not sure about other platforms.
