Simple PHP URL shortener

Requires PHP ≥ 5.4.0 or higher.

Installation

  1. Download the source code as located within this repository, and upload it to your web server.
  2. Use database.sql to create the redirect table in a database of choice. (Do not delete the INSERT statement on line 10 as it is needed to initialize the database.)
  3. Copy config.exemple.php to config.php and enter your database credentials + social IDs/default URL.
  4. For additional security through obscurity™, consider renaming shorten.php to a secret file name of your choosing and tweaking the .htaccess file (line 3) accordingly.

Features

  • Redirect to Twitter when given a numerical slug, e.g. http://mths.be/8065633451249664 → http://twitter.com/mathias/status/8065633451249664.
  • Redirect to your Twitter account when @ is used as a slug, e.g. http://mths.be/@ → http://twitter.com/mathias.
  • Redirect to your Google Plus account when + is used as a slug, e.g. http://mths.be/+ → https://plus.google.com/u/0/116553353277057965424/posts.
  • Redirect to your main website when no slug is entered, e.g. http://mths.be/ → http://mathiasbynens.be/.
  • Redirect to a specific page on your main website when an unknown slug (not in the database) is used, e.g. http://mths.be/demo/jquery-size → http://mathiasbynens.be/demo/jquery-size.
  • Ignores weird trailing characters (!, ", #, $, %, &, ', (, ), *, +, ,, -, ., /, @, :, ;, <, =, >, [, \, ], ^, _, {, |, }, ~) in slugs — useful when your short URL is run through a crappy link parser, e.g. http://mths.be/aaa) → same effect as visiting http://mths.be/aaa.
  • Generates short, easy-to-type URLs using only [0-9a-z] characters.
  • Doesn’t create multiple short URLs when you try to shorten the same URL. In this case, the script will simply return the existing short URL for that long URL.
  • DRY, minimal code.
  • Correct, semantic use of the available HTTP status codes.
  • Can be used with Twitter for iPhone. Just go to Settings › Services › URL Shortening › Custom… and enter http://yourshortener.ext/shorten.php?url=%@.
