Chain function calls?

It doesn't appear PHP4 supports this?
So I have to break away from my zeal for OOP and use data member chaning instead or am I missing something here?
Is there a way you can indeed chain function calls?
Thanks

I just googled it seconds before your post
So, PHP 5 supports function call chaining?
Cheers

I'm a hardened OOP guy...for years I had private, public and protected access control then I started developing in PHP...
I'm
really no keene/kean(e)?? on allowing access to data members, never mind force the technique by making it mandatory
I really don't like that ad hoc hack either...thats what I call spaghetti code...
Who introduced eval() anyways???
Dynamic programming is best left out of imperative languages and best left for artificial intelligence or viruses. IMHO anyways
I'll stick with my mutators/accessors and just use the old trusty re-assignment approach instead of function chaining
When most of the world upgrades to PHP5 (why is it taking so long) I'll then possibly re-implement using chaining...

I'm not sure that chaining is such a good idea anyway -- except maybe for accessors. I think it seems cooler than it is. There is an assumption that every method returns a valid object. I still prefer to explicitly assign to vars.

As do I, however sometimes, IMHO, syntactically it's cleaner and makes obviouse sense without the clutter of a few more lines...
Kinda like initializing multiple variables to zero using:
Code: Select all
$var1 = $var2 = $var3 = $var4 = 0;
As opposed to:
Code: Select all
$var1 = 0;
$var2 = 0;
$var3 = 0;
$var4 = 0;
When working with a DOM I often use chaining because the model is rendered visually for you and you can also use raw HTML to develop a mental picture of what exactly the chain commands are doing.
In cases where I'm working with a verbose class hierarchy (such as a framework) I tend to use seperate variables just for clarity sake.
