I don't know if I can ask this question here. I usually mistake, but...
I every want the "array json style" on PHP, like $a = [1, 2, $value];. But I read that PHP developers HATE this idea because too many people wants, and they thought it best not to offer the feature.
The question is: WHY? I thought that might conflict with some existing feature, but I could not think of any.
Additional: someone know what is the PHP dev features list (where it is presented and discussed)?
There is a possibly that this will be added in PHP 5.4. As you can see, Andrei Zmievski, Andi Gutmans, and Rasmus Lerdorf, all very important people in PHP's development, voted in favour of the new syntax.
You can see all feature requests that are being proposed and voted on here.
PHP does not have this kind of arrays at all (that is - sequences of elements that are indexed with numbers). It would be strange to have a notation for something that does not exist.
Neither has PHP the kind of arrays that - in JSON - look like this: {a:"asd",b:"sdsfsdf"}. That's because what we have in PHP is a mix of the two: an array that is at the same time indexed with integers and with strings. And none od the two notations look convincing (or are acceptable as JSON):
$a = ["a","b", 36=>"test", "name"=>"Filip"];
$b = {"name": "Filip", 36: "test"}
One 'why not', redundant additional syntax.
array(1,2,$value)isn't good enough for you?$a = array(1, 2, $value);? The only difference is you put array before it and use parenthesis instead of curly braces.[1, 2, {3: 4}]vs.array(1, 2, array(3 => 4))
