Programming languages

Several programming languages are used for the CouchSurfing website.

HTML

• HTML reference manual
• Style sheets

PHP

Some good PHP resources:

• PHP.net
  • tip: php.net/str_replace will explain everything about str_replace
• Book: Teach yourself PHP in 10 minutes. Handy reference for getting up to speed really fast.

• Aidan's PHP Repository - a library of useful classes, functions etc; all code "resides in the Public Domain, you are free to use and modify it however you wish"

MySQL

Some good MySQL resources:

• MySQL Documentation
• MySQL 3.23, 4.0, 4.1 Reference Manual
• MySQL 5.0 Reference Manual

Regular Expressions

• Use regextester in case you want to use regular expressions (really powerful, but sometimes a bit tedious.)
• Regular Expressions syntax from Python Library Reference so with Python code examples, but applicable in PHP just as easily.

Not used on a regular base for CS

But it's good to know who knows what in case there's need for it.

Python

• Expert: Guaka
• Intermediate: Anu

Bash, shell programming

• Basic knowledge: Guaka, Anu
