Script for uploading ZIP file and unzip it on the server

/ Published in: PHP
Save to your folder(s)
Easy PHP script for uploading and unpacking zip files to the server much faster

Steps to follow:

1. create folder on the webserver called "zipper" or something else
2. copy the following PHP code into a file called "zipper.php" into this folder
3. use the url to this file to start the little script
4. select a zip file from your harddisk and go for it
5. after upload a directory exists in the folder "zipper" from step 1

with ftp program (like Filezilla) you can easily move the content to the directory of your choice (that's all), which goes much faster
