if(is_resource($zipHandler)) {
while($zipEntry = zip_read($zipHandler)) {
$fileName = zip_entry_name($zipEntry);
echo("File Name: " . $fileName);
echo "\n" ;
}
zip_close($zipHandler);

<?php
class ZipExample {
public function processZipArchieve() {
/* Invalid zip archieve or an invalid file path */
$zipHandler = zip_open("./invaid.zip");
zip_close($zipHandler);
