Solution 1
<?php
$zip = zip_open("zip.zip");
if ($zip) {
while ($zip_entry = zip_read($zip)) {
$fp = fopen("zip/".zip_entry_name($zip_entry), "w");
if (zip_entry_open($zip, $zip_entry, "r")) {
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
fwrite($fp,"$buf");
zip_entry_close($zip_entry);
fclose($fp);
}
}
zip_close($zip);
}
?>
Solution 2
See this http://www.php.net/manual/en/ziparchive.extractto.php
$zip = new ZipArchive;
if ($zip->open('E:\pathto\zip\ashok_subedi.zip') === TRUE) {
$zip->extractTo('E:\pathto\extrac\myzip');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
Solution 3
You can upload this file to your web-server and run it. It will ask you to choose a zip file for unzipping, and you could specify the path where you want to unzip. In case you want to unzip the file in the current location, just leave the unzip path blank. On finishing the unzipping, it will give you feedback, too.
