php single function with multiple names / aliases

Question

This isn't really important but the question is more one of curiosity.

Is it possible to alias a function or define two names for it.

I know this works:

function real($p1=array(), $p2=null, $p3='default'){
  return 'something';
}

function aliasForReal($p1=array(), $p2=null, $p3='default'){
  return real($p1, $p2, $p3);
}

Is there a less verbose way to alias another function?

something like

function (real||aliasForReal)(...){

or

function aliasForReal extends real;

There are a couple of places I need to do this and the working method above just feels a bit dirty to me.

For instance:

using names like (begin and start) interchangeably for one function and (end and stop) for another.

Note that it *is* possible to do this starting from PHP 5.6 (which is currently in beta). I have added [an answer](http://stackoverflow.com/a/23426311/50079) to the dupe. — Jon, May 02 '14 at 10:49

function real($p1=array(), $p2=null, $p3='default'){
  return 'something';
}

$real1 = 'real';
$real2 = 'real';
// etc

You can call $real1(...)
