Question

This is a little bit of a hard problem to explain, so ill show you instead. If you look below you will see valid JSON.

{
    "data":{
        "0":{
            "action_id":"1",
            "date":"2012-04-10 15:07:38",
            "action_type":"1",
            "action_text":"Some one got blamed!"
        },
        "1":{
            "action_id":"2",
            "date":"2012-04-10 16:18:05",
            "action_type":"1",
            "action_text":"Testing multiple items for AJAX"
        },
        "total":2,
        "ajax_message":"Success",
        "ajax_status":"0",
        "success":"true"
    }
}

But for the application were using it cannot handle the “0”: ,”1″, it instead just wants it comma separated .

My current code to generate this is:

while ($r = mysql_fetch_assoc($q)) {
        $array[] = $r;
    }
json_encode($array);

Fairly simple and raw stuff at the moment. But i think i may have to write a json_encode for myself in order for it to print it like this…..

Any help would be greatly appreciated

NOTE: This is a valid form(written by hand):

{
"data": [
{
"action_id": "1",
"date": "2012-04-10 15:07:38",
"action_type": "1",
"action_text": "Some one got blamed!",
"fb_id": "760775384"
},
{
"action_id": "2",
"date": "2012-04-10 16:18:05",
"action_type": "1",
"action_text": "Testing multiple items for AJAX",
"fb_id": "760775384"
}
],
"total": 2,
"ajax_message": "Success",
"ajax_status": "0",
"success": "true"
}

The problem is that your numeric keys (0, 1) are at the same level in the hash as named keys (total, ajax_message, etc). Instead of doing this:

$a = array();
while ($r = mysql_fetch_assoc($q)){
    $a[] = $r;
}
$a['key'] = value;

Do this:

$a = array();
$a['rows'] = array();
while ($r = mysql_fetch_assoc($q)){
    $a['rows'][] = $r;
}
$a['key'] = value;

If every key in the array ($a['rows'] in this example) is numeric, json_encode() will output it as a [{list}, {like}, {this}]
