  @ Brett Zamir: Yes we have a FAQ! : ) Let's just take a moment to enjoy that fact :D

Ok, good.

I've changed the navigation a bit according to your ideas.

As far as linking/making wiki pages for individual functions; I'm not too fond of that idea as there already is a lot of information about functions in the comments, and I think I'd like to keep it centralized that way.

And we can't move all function comments to the wiki cause that would probably raise the bar for people to leave any comment at all.

  @Kevin: also, btw, thanks for adding the link!

  @Kevin: Now that we actually have a FAQ on the wiki (at least the beginnings of one), do you want to link directly to that instead of the wiki? (or maybe call it "FAQ/wiki" to indicate that both are available there) I think it's important to indicate that we have FAQ answered there. Also, what do you think of making automated links on the function pages to the wiki for letting users contribute their own non-PHP variations, tips on use, etc.?

  Link is on it's way!

  It seems the comments problem is fixed now. And, sure, go ahead and add a link to the wiki; that'd be great...

  @ Brett Zamir: The comments, no I'm not having those issues. Could you by any chance supply the errors?

btw I removed the social javascript. maybe that fixes some issues as well.

  @ Brett Zamir: Thanks for baring with me Brett. I must say I'll sleep a little bit better knowing there's 1 less thing I need to maintain & think of.
I'll add a link to the github wiki and we'll see how it goes OK?

  @Kevin: Also, by the way, do you know why phpjs.org hangs seemingly indefinitely after posting a comment here? I seem to always have to refresh the page... (there are also some red warnings displayed in the interim)

  @Kevin: I guess using the GitHub wiki would be ok, but it really gets under my skin when these sites, instead of using the powerful and well-known Mediawiki, add frustratingly deficient wikis of their own (and I'm already unhappy with Git itself, or rather, the current lack of GUI tools to work with it as well as with Subversion). But to be fair to you (and it is not a big deal for the limited documentation we need), the GitHub wiki should work fine for this.

  I understand, and have by now run into the problem myself (array_diff with un-indexed arrays gives forced numeric indexes to the resulting array).
If you choose to use generic Objects for arrays throughout, the implode() function should reflect this as well.

I'll append a comment there.

  @ Brett Zamir: We could probably start one in the wiki.
What do you think about hosting the wiki here:
http://wiki.github.com/kvz/phpjs ?

this way i wouldn't have to worry about updating media wiki, accountmanagement, and backups ?

   @Itsacon: We are really kind of forced in most cases to treat arrays as objects in order to preserve PHP-like behavior of preserving keys (such as array_diff), including numeric keys. For example, to take Example #1 at http://php.net/array_diff , note that the key returned is '1' (with the value 'blue'). To do this with a regular array, we would either need to force the array to be of size 2, i.e.: "[undefined, 'blue']" or lose the key=1 information, i.e., "['blue']".

I also see that I hadn't updated our array_diff example to show an object being returned, so it was showing an array being returned instead, but that is now fixed in Git.

If you really want to be able to return genuine arrays and don't mind losing key information (or don't mind getting an array which has "undefined" place-holders for empty numeric keys causing the size of the array to be inflated), then we could add some code to allow you to do something like:

1

ini_set('phpjs.objectsAsArrays', 0);

   There's a compatibility problem with this function and functions that take Array inputs (and check for it), like implode().
This is caused by this line:

1

var arr1 = arguments[0], retArr = {};

1

var arr1 = arguments[0], retArr = new Array;

Re-Ordering the Index

   ///////////////////////////////////////////////////////////
/*
Sanjoy Roy's comments:
-------------------------------
I have added a counter variable (cntr) and return array returns ordered array.
This will help to get rid of 'undefined' values in the list when we use them in our program.

  @ Ates Goral: All together superb contributions. Greatly formatted and very consistent. I also like that you've included the example-return pairs in the comments. Thanks a LOT!
