Description nadavvin 2013-09-16 07:02:15 UTC 
the support in "Const array/string dereference":
https://wiki.php.net/rfc/constdereference

is not implemented good.

while this is valid in netbeans:

echo array(2,3)[1];

this isn't:

function a(){
	return array(3,4);
}
echo a()[0];
Comment 1 Ondrej Brejla 2013-09-16 07:43:43 UTC 
Not sure if it should work. Documentation [1] just talks about "array and string literals". Function dereferencing is not mentioned anywhere (or at least I didn't saw it anywhere...it's not in RFC [2] either, there are just literals too).

[1] http://www.php.net/manual/en/migration55.new-features.php
[2] https://wiki.php.net/rfc/constdereference

So incomplete for now...I'll try to find some more info.
Comment 2 nadavvin 2013-09-16 08:41:13 UTC 
It should work since it's work.

php 5.5 run it without any warnings:

php > function a(){return [3,4];}
php > echo a()[1]
php > ;

Official example:

http://il1.php.net/manual/en/language.types.array.php

Example #7 Array dereferencing
<?php
function getArray() {
    return array(1, 2, 3);
}

// on PHP 5.4
$secondElement = getArray()[1];
Comment 4 Ondrej Brejla 2013-09-16 08:47:38 UTC 
Ok, I just tested that in NB and just "Language feature not compatible..." error occurs, so it's supported (it means it's parsed correctly), but wrong hint is used for PHP 5.5 project type. I'll look at it.
