PHP Bug Type: JSON related
Bug description: json encode creates objects from array with gaps in the index
Description:
------------
When encoding an array with sequental keys. Everything works out fine.
When encoding an array with gaps between the keys. The json encoder creates
an object instead of an array. Wich maybe ideal in some places. But it's
inconsistant with the JSON javascript parser at json.org. I selected the
PHP 4.4.7 version. But also tested in PHP 5.2.3 with the same result.
In json.c the following code is causing this:
--- ext/json/json.c.orig 2007-08-14 22:38:20.000000000 +0200

if (i == HASH_KEY_IS_STRING) {
return 1;
- } else {
- if (index != idx) {
- return 1;
- }
}
idx++;
}
Reproduce code:
---------------
<?php
/**
* Create an array with ordered keys from 0 to 1
*/
$main = array();
$element1 = array();
$element2 = array();
$element1[0] = "foo";
$element2[0] = "bar";
$element2[1] = "test";
$main[0] = $element1;
$main[1] = $element2;
echo "Result in array: " . json_encode($main) . "\n";
/**
* Create an array without ordered keys from 0 to 2
*/
$main2 = array();
$element1 = array();
$element2 = array();
$element1[0] = "foo";
$element2[0] = "bar";
$element2[1] = "test";
$main2[0] = $element1;
$main2[2] = $element2;
echo "Result in object: " . json_encode($main2) . "\n";
?>
Expected result:
----------------
Result in array: [["foo"],["bar","test"]]
Result in object: [["foo"],["bar","test"]]
Actual result:
--------------
Result in array: [["foo"],["bar","test"]]
Result in object: {"0":["foo"],"2":["bar","test"]}
