This can't go into PHP 5.4.0 in any case, because it is a feature addition and the release is already in RC. Nikita On Tue, Dec 13, 2011 at 7:16 AM, Laruence <laruence@php.net> wrote:

"foobar"["foo"] - Why not "undefined index"? On Tue, Dec 13, 2011 at 10:20 AM, Nikita Popov <nikita.ppv@googlemail.com>wrote:

Exactly. The index/key "foo" does not really exist in the string "foobar" because a string is more an indexed array of characters than a combination of substrings (as the key "foo" could suggest). "foobar"[3] has a well-defined meaning, but "foobar"["foo"] sounds strange for me :-). Which semantics do you attached to this syntax? Cheers.

I would reset the vote and make the vote for this change to apply to trunk instead. There is no reason to delay this decision, even if it is too late for 5.4 :) Cheers,

What happens in your patch if something like ['foo', 'bar'][1] is used in write context?

this patch will not allow that, in write context lead to syntax error.

I have always wondered why array dereference does not just work on arbitrary expressions in PHP like other operators do. Even with the latest modification that allows dereferencing function calls, this works: md5('')[0] but this results in a parse error (syntax error, unexpected '['): (md5(''))[0] Then there are expressions like ('a'.'b')[0], all sorts of combinations of operators... Why not just treat any 'expression[expression]' as an array dereference as other languages do?
>> echo "foobar"["foo"][0]; > > "foobar"["foo"] - Why not "undefined index"?
"foo" is converted to an integer, yielding zero. 'Undefined index' seems to make more sense to me but PHP 5.3 behaves the same way.
