20 Jun 2011, PHP 5.4.0 Alpha 1 -> Added array dereferencing support. (Felipe)
11 Nov 2011, PHP 5.4.0 RC1 -> Added class member access on instantiation (e.g. (new foo)->bar()) support. (Felipe)

Many thanks for Felipe.
It would be nice to add: Array element access on instantiation
array()[$x] and [][$x]

Then everything would be fully useful, but not in part.

(edit summary)

see https://wiki.php.net/rfc/constdereference

>> echo array(1, 2, 3)[0]; //output 1
>> echo "foobar"[2]; //output o
>> echo "foobar"["foo"][0] // output f
>> works.

Excellent! Have you tested it with short array constructor?
echo [1, 2, 3][0]; //output 1


Are there any opportunities to make it public in the final PHP 5.4?

support (of course).

yes, but it need to be disscussd first ;)

/Summary change/ Array -> Array/String

I'm all for it.

example: short switch/case alternative
--------------------------------------

<?php

echo 'ABC'[$i]
// or
echo ['A','B','C'][$i]

?>

is equivalent to long:

<?php

switch ($i) {
    case 0:
        echo "A";
        break;
    case 1:
        echo "B";
        break;
    case 2:
        echo "C";
        break;
}

?>

Dmitry, could you look at this please? thanks
patch and test list in: https://wiki.php.net/rfc/constdereference

All existing test passed.

I would say the patch is wrong. It misses the possibility of container_ptr separation in zend_fetch_dimension_address_read(). It also won't work with ZEND_FETCH_DIM_FUNC_ARG.

dmitry, thanks very much for pointing that out, I will try to fix these issues. :)
