Guys, we really need this feature to make our code beautiful.

Now:
function get2nd(){
    $tempArray = explode(',', array('a','b','c'));
    return $tempArray[1];
}
Better:
return explode(',', array('a','b','c'))[1];
or:
return array_get(explode(',', array('a','b','c')), '1');

Thanks.

Developer guys, we php programmers indeed need this function 
to direct access element of the function/method returned array.

Sometimes i work around this so:
echo ${!${''}=&explode(',','a,b,c')}[1];

maybe it's the shortest hack code to mimic direct access,
but it's ugly, we really need to realize it in the php build-in syntax
supporting.

doesn't fix the bug, but a workaround:

function array_val($array, $key) {
        return $array[$key];
}

then you can do things like:

var_dump(array_val(array('a', 'b'), 1));

Supported dereferencing array indeces on arbitrary expressions.

Currently you can only dereference array indeces on variables
directly:

$a = array('a', 'b');
var_dump($a[1]);

but this does not work

var_dump(array('a', 'b')[1]);

neither does this:

function returnArray() {
    return array('a', 'b');
}
var_dump(returnArray()[1]);

or this:

$value = ($ns == 'foo' ? $thisArray : $thatArray)[0];
