This PHP class is a fairly faithful implementation of the algorithm (the web page of which can be found here). The primary use of stemming words is in keyword indexing, if you're building a search application.

This mutex (mutual exclusion) class can help to avoid the simultaneous use of a common resource (concurrency problem)

Perl and PHP are two of the most popular languages for creating dynamic web content. The PHPerl Project aims to combine the power (and extensive code libraries!) of both languages.

Function used to make using mod_rewrite easy. The file has exmaples on how to use it and how to add an entry into you .htaccess file

This is the "top-end" of Dirty Dirz, coming soon, and as such it assumes an existing directory structure. It is also unable to chmod files so this has to be done manually, on your web host's control panel. Well now that we know what it doesn't do let's find out what it does. F-ystem is a flat-file conection handler. It's capable of copying, reading and writing to files. It works from your website's root folder in every instance. This is because I split the full path into two parts, root and relative. It's really no big deal just that you reference your root folder with a string similar to this /home/site/public_html/ in a file called F-ystem.settings.php. Now when you want to read a file, let's say Readme.txt, in a sub-folder, let's call it Bob, of your root folder(ex. path mentioned above). You use the string 'Bob/Readme.txt' as your target_path. The fystem function will append this target_path to the string you specified as your root folder. You can also specify the folder Bob as your "root folder" in the settings file(ex. /home/site/public_html/Bob/ ). The copy_source path is treated in the same way. If you do not leave the trailing slash on your root folder string you will be unable to correctly reference your files. Why? It would be because when you use a "/" charactor as the first char in file system functions, the ones internal to PHP, it is treated as the full path from your parent folder
