Hello,

2013/5/1 Stas Malyshev <[email protected]>



The result is the same with "new ReplectionMethod('foo','bar')". The added
value is that it can be statically checked.

well... yes and no.


Take the Symfony2 example:
you want to reference ^$task->task with autocompletion in your IDE?

This won't work, because Task::$task is a protected property. Symfony2 does the magic for you and automagically accesses the getters and setters.
This probably won't work with property references, since you can't get the getters and setters for it (except relying on the name of the property as string and manipulating it).

Soo... I guess, for this feature, to be useful, we need object accessors first (which were recently rejected by vote)?


Cheers
Jannik

Hi!


PHP has functions that can be result of __call or arbitrary code that
implements fcall handler in an extension. What would be returned then?

In C#, they had the intention to introduce the operator infoof(...) to get
the reflection, not only of properties, but of virtually everything in the
language. They abandoned the idea because it is really hard to do that for
overloaded functions and they did not want to do all that work for a half
baked feature:

However, PHP does not have overloaded functions, which makes things
significantly easier, so maybe it is worth examining the idea.

It is certainly not worth overloading the XOR operator for.

Hi!


You probably have use case for that, and it should be pretty easy to
write a class that does that, but why it should be in the language? It
certainly doesn't look like something sizeable portion of PHP devs would
do frequently.
