URL Shortening Script

Here is a demo of my url shortening script. It let your visitors to make short redirections of their very long url's (for example it is useful for twitter users where they are limited to 140 characters). Script is made to be as simple as possible. HTML is separated from PHP so it may be customized by editing one HTML file without touching any PHP code! It do not need MySQL database - all data is stored in the file system. Users are redirected by .htaccess file to desired shortcut. Additionally there is administrator backend module to manage (edit/add/delete) url shortcuts. Below you may click for demo installed on my dev server.

How to enable error reporting in PHP script

If error reporting is disabled by default on your host you have two solutions.
First is to add to your PHP script this little piece of code:

<!--?php 
  error_reporting(E_ALL);
  ini_set("display_errors", 1);
  // the rest of your script...
?-->

Additionally it is very useful to enable E_STRICT reporting level as well (not included in E_ALL). E_STRICT run-time notices, enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code. To turn it on your code should look like this:

<!--?php 
  error_reporting(E_ALL | E_STRICT);
  ini_set("display_errors", 1);
  // the rest of your script...
?-->

But putting this code on the top of your script will not catch any parse errors. A missing ")" or ";" will still lead to a blank page. This is because the entire script is parsed before any of it is executed. If you are unable to change php.ini (that would be the best solution) and set in it

display_errors On

then there is a possible workaround (found on comments on php.net website). This code would solve this problem:

<!--?php 
  error_reporting(E_ALL | E_STRICT);
  ini_set("display_errors", 1);
  include("file_with_errors.php");
?-->

You may go even further and make a little debug script with error reporting (when it is disabled for the rest of your scripts). Just create a file called "debug.php" with this content:

<!--?php 
  error_reporting(E_ALL | E_STRICT);
  ini_set("display_errors", 1);
  include($_GET["file"]);
?-->

Then you will be able to execute any script on your web host just by calling "debug.php" with urls like this
http://domain.com/folder/debug.php?file=file_with_errors.php
http://domain.com/folder/debug.php?file=subfolder/file_with_errors.php
http://domain.com/folder/debug.php?file=../file_with_errors.php

Second alternative soulution is to edit your .htaccess file. It would enable error reporting for all files in current directory. All you need to do is to simply add the following lines:

php_value display_errors 1
php_value display_startup_errors 1

PayPal shopping cart

Very simple to use PayPal shopping cart. It may be customized by CSS sheet to your needs. You can use any currency supported by PayPal and define any type of products or services to sell. There are two types of groups for selling items - with radio button (client can choose only one option from group) or with checkboxes (client can choose many options from the group). Number of groups in cart is unlimited! All orders details are available thru admin. Additionaly descriptions over and under shopping cart may be customized with simple templates. Script is written in pure PHP and data is stored in MySQL database.

Demo shows example of using this cart for ordering “Wedding photographer”. If it doesn’t, probably someone have already been testing it… Anyway database resets every 24h so I am not going to change this description… :D If you want you may test it by clicking links below.
