directly using an index on returned array

[Erwin Moller]

Hi,

Consider the following code:

-------------------------
function giveArr(){
return array("one","tw o","three");
}

echo giveArr()[1];
// I am hoping for "two"
-------------------------

This syntax clearly doesn't work.
Does anybody know if that is possible?
If so, what is the right syntax?

(Of course I can store the returned array in some variable, and then use an
indexing on that variable.)

I am curious if the above construct is possible (in another syntax
obviously) with PHP.

TIA

Regards,
Erwin Moller

Re: directly using an index on returned array

Just out of curiosity why would you not want to use something like


function giveArr($n){
array("one","tw o","three");
return array[$n];
}

echo giveArr(1);

Don't know of any other way, but I'm not a pro...

No reason.
I don't actually need this right now.
And I can also store it in another var as described, and use an index on
that var.

This is just something I was trying and couldn't do this way, so I thought I
might ask in here.

Not really. There are some options related to it, like the list()
construct.
Also, for this particular case one might use vprintf('%2$s', giveArr());
