anyone knows ....

Which PHP Framework was used to create Elgg, if any?

Popular PHP IDEs are :-

• Eclipse
• NetBeans
• Aptana

I believe (think) the Elgg Core Team uses Eclipse.

'Syntax of Elgg..' ? --
This is not the same as the syntax of a language.

The big difference from Elgg 1.7 => 1.8 is the UI --
the CSS, Views System, the API, function calls needed to invoke
Elgg's code power/features..

The best way to 'Learn Elgg' is to browse and study thru the Core Code;

Go thru the documentation areas :-

• http://docs.elgg.org/wiki/Main_Page
  
• http://reference.elgg.org/ (or lso my own http://elggapi.hackersgalaxy.com/) 

Elgg does not use a framework (like Symfony or Zend or CakePHP). Also the API did not change that much between 1.7 and 1.8. We added a new menu system and we've been converting the get functions to take associative arrays rather than long lists of parameters.

Oh, and I think only Evan uses Eclipse on the core team. I'm a NetBeans user and I think Brett recently started using NetBeans more.

As per Cash's advise, I started using NetBeans and I llike it.

I am using Eclipse becuase it has a big number of plugins and a vibrant community support :-)

I am using eclipse too.. many many crashes and freezes -_- (debian, eclipse 3.5.2)

13net you can increase the memory used by java....

I used Eclipse and XDebug for php scripts, but it is more difficult with Elgg pages. Any idea about how to debug Elgg pages?

I should have qualified earlier - as Cash pointed out " API did not change that much between 1.7 and 1.8. We added a new menu system and we've been converting the get functions" . There may be 'visual' changes extensions in the API - the way they are called..

And.. in spite of all these IDEs floating around and having almost all of them sitting here on my M/C - I still use plain NotePad++ for all me development ;) Something to so with with having to be able to debug while 'knowing' the code I'm dealing with. If I can't eyeball the code and figure out some bugs in a few minutes.. the situation is not very good, and using an IDE does not help me faster ;-o
