Question

I am combining two arrays then encoding into JSON for output. I get a funky value in JSON output at the start of the second array. This is the "0": item. I can’t figure out where this is coming from.

Combine the arrays and output json:

$combine = array_merge(array('array1'=>$bay_events, array('array2'=>$key_events)));
$finish = json_encode($combine);

$callback = $_GET['callback'];
echo $callback.$finish; 

JSON output:

{
    "array1": [
        {
            "event_id": "3914",
            "event_name": "Test"
        }
    ],
    "0": {  <--- this should not be here
        "array2": [
            {
                "event_id": "3913",
                "event_name": "Testssdgs This Is how"
            }
        ]
    }
}

I cant figure out where "0": is coming from. Help?

Answer 1

You are not using array_merge the proper way

The problem

• You where trying to merge only one array
• The second element in the only array refers to another array wich resulted in another index 0

Explanation

$combine = array_merge(array('array1'=>$bay_events, array('array2'=>$key_events)))
                         ^      ^                    ^
                         |      |                    |       
      Only One array ----+  Fist Index           Second Index Another array

This is the proper way to use array_merge

$combine = array_merge(array('array1'=>$bay_events), array('array2'=>$key_events));

Or Just remove it totally

$combine = array('array1'=>$bay_events, 'array2'=>$key_events);
