echo "Actual Filesize: " . zip_entry_filesize($zip_entry) . "n";
echo "Compressed Size: " . zip_entry_compressedsize($zip_entry) . "n";
echo "Compression Method: " . zip_entry_compressionmethod($zip_entry) . "n";
if (zip_entry_open($zip, $zip_entry, "r")) {
echo "File Contents:n";
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
echo "$buf\n";
zip_entry_close($zip_entry);
}
