No, it creates local variables. These were meant to be used in some complex
processing directly following, something like
if ($foo == 3)
if (some_func($bar) == 4 && $baz ==2) ... // I mean a lot of conditions
or other uses following.
The line
return $foo."-".$bar."-".$baz;
only should illustrate, that the example is working correctly.

I didn't expect this. Are you sure? I mean php is an interpreter, or does it
compile things? If it is a pure interpreter, I would expect the parser
itself using eval a lot. So why should this be especially expensive? Do you
have any hints on something I might read regarding this?

Of course, but s. above.
Well, I think I'm somehow misusing the language. It is my own decision how
to create the array. Probably it's better to create the array as array("foo"
=> 1, "bar" => 2, "baz" => 3) and use extract on this.
