Description:
------------
When using objects it can become very ambiguous what is occuring once
you start using variable variable names. The reproduce code shows a
non-useful example of where this might occur.
A concise example of the problem:
$ob->field[0] ==> array[0] ==> item
$ob->$field[0] ==> $ob->'b' ==> array
Being able to use brackets or something similar to force the ->
operator to act before the [] would allow for a choice of functionality
in the second example and provide the ability to make the code clearer.
$ob->($field[0])
($ob->$field)[0]
Both of these examples are currently not possible, a syntax error,
unexpected ( or [ occurs.
Reproduce code:
---------------
<?php
class Arrayise {
function __get($name) {
return array($name);
}
}
$ob = new Arrayise;
$field = 'bar';
var_dump($ob->$field[0]); // b
var_dump($ob->field[0]); // bar
?>
