在PHP中提取ZIP，覆盖所有内容

Question

I'm extracting server side .zip using this:

<?php
$unzip = shell_exec("unzip zipp1.zip");
?>

It's working fine, but it doesn't overwrite existing files (and I need it!).

Everything is in the same folder, chmod 777.

Can I add something to fix? Tnx!

Answer 1

If you really need to use shell, you can write unzip -o zipp1.zip .

However, PHP has a library for working with Zip archives, called ZipArchive : http://php.net/manual/en/class.ziparchive.php

There you can extractTo which overwrites by default: http://php.net/manual/en/ziparchive.extractto.php

It's usually a good security practice to disable shell_exec() , so using PHP's libraries is recommended.
