JSON array unset

Question

First of all, I really don't know if that kind of topic exist. But I searched a lot and now I am here.

My question about parsing. For example I would like to unset some items.

$now = array();
$now[0]['name'] = "Hello1";
$now[0]['si'] = "BumBum1";
$now[1]['name'] = "Hello2";
$now[1]['si'] = "BumBum2";
$now[2]['name'] = "Hello3";
$now[2]['si'] = "BumBum3";
$now[3]['name'] = "Hello4";
$now[3]['si'] = "BumBum4";

echo json_encode($now)."<br>";

unset($now[0]);

echo json_encode($now);

And the output:

[{"name":"Hello1","si":"BumBum1"},{"name":"Hello2","si":"BumBum2"},{"name":"Hello3","si":"BumBum3"},{"name":"Hello4","si":"BumBum4"}]

{"1":{"name":"Hello2","si":"BumBum2"},"2":{"name":"Hello3","si":"BumBum3"},"3":{"name":"Hello4","si":"BumBum4"}}

And my the JSON file turns to messy code. Appears numbers and etc. Any ideas how to solve this.

Tried with objects. Same problem.

You need to "reindex" the array (use array_values() function).

//unset..
unset($now[0]);

//reindex
$now = array_values($now);

//display as before
echo json_encode($now);
