php-put-file-store

A small script for a constrained PHP web hosting environment, allowing to send files to the server via PUT requests. I use this script to backup my files to my web server and make use of the unused space.

Normally people will use rsync for this but it is not possible with my web hosting server because of a number of restrictions. This serves a cheap and simple alternative to do the same thing.

Though the client script here is written in Python, it is not difficult to rewrite it in another language.

Setup

1. Upload both server.php and pass.ini to server.

• Each line in pass.ini defines a directory to store a set of files.
• The password is for authenticate PUT (file store) requests.

2. Modify variables backup_client.py to point to your server.
3. Whenever you want to send files to the server, run backup_client.py.

Note: For simpicity no directory structure is preserved in this script, i.e. storing only files in a single directory is recommended.

How Does It Work?

1. The server verifies the area name and password.
2. The client sends a local file list to server.php for checking which files are outdated (determined using the filename and the size of the file only).
3. The server returns a list of files the client should upload.
4. The client uploads files with PUT requests one-by-one.

Requirements

• PHP
• Python 3

Disclaimer

These scripts are experimenting with uploading with HTTP PUT requests (sending with Python and receiving with PHP). For scenarios requiring security and performance, please use other sophisticated methods instead.
