PHP links

In class we learned of

• PHP.net for the official site of PHP.
• tizag.com for a PHP tutorial (http://www.tizag.com/phpT/)

As well, the following two links are php portals of sorts with many categories... resource and reference.

• Top of the Google search result is php.resourceindex.com. I just looked around and for example found some quick answers to code and how to write the functions. Doesn't seem to be any "spam" in this collection of links.
  
• I somehow came across www.hotscripts.com/PHP Warning: there is a lot of junk to filter through. Perhaps there is something good in the Scripts and Programs section.
