That could work. Since arrays in javascript are numeric only, one
could determine if a structure is an object or an array. However,
there are no functions to determine if an array contains associative
items, so that would have to be implemented in userland.
Being able to encode arrays to JSON objects would have a lot of
benefits. For instance, one could create JS functions or entire
object structures which otherwise could not be expressed through PHP
objects.

Exactly what I was going to say.
The one thing I'd like to see change is having JSON "objects"
decoded into PHP associative arrays, not PHP objects, as is done
in the current PECL implementation. Here's what happens now via
PECL JSON:
Maybe introduce an optional second argument "decodetype" to
json_decode() where you could pass on a constant like JSON_ARRAY or
JSON_OBJECT?
For example:
$assoc_array = json_decode($json_string, JSON_ARRAY);
$object = json_decode($json_string, JSON_OBJECT);
However, I don't think such a feature should hold this from going
into core.
========= script =========
<?php
echo '<pre>';
$enum = array('foo', 'bar');
$assoc = array('f' => 'foo', 'b' => 'bar');
$obj = new c;
echo "\nInitial PHP:\n";
print_r($enum);
print_r($assoc);
print_r($obj);
$pecl_enum = json_encode($enum);
$pecl_assoc = json_encode($assoc);
$pecl_obj = json_encode($obj);

print_r(json_decode($pecl_enum));
print_r(json_decode($pecl_assoc));
print_r(json_decode($pecl_obj));
?>
========= output =========
Initial PHP:
Array
(
[0] => foo
[1] => bar
)
Array
(
[f] => foo
[b] => bar
)
c Object
(
[f] => foo
[b] => bar
)
JSON encoded:
["foo","bar"]
{"f":"foo","b":"bar"}
{"f":"foo","b":"bar"}
PHP decoded from JSON:
Array
(
[0] => foo
[1] => bar
)
stdClass Object
(
[f] => foo
[b] => bar
)
stdClass Object
(
[f] => foo
[b] => bar
)
