[0] => Array
(
[id] => 2
[brokerid] => 2
[agentid] => 3
[addedby] => 1
[get_agent_details] => Array
(
[id] => 3
[name] => kenang
[ic] => 932132923

I have one set of an array, and I loop it and restructure match the data based on ID. After that I will try to merge the same data into one array, I able add into one array. But it will not combine as one. The correct result should be as below.
[get_agent_details] => Array
(
[0] => Array(
[id] => 3
[name] => kenang
[ic] => 932132923
[phone] => 2313123
),
[1] => Array
(
[id] => 4
[name] => ivan
[ic] => 32992131
[phone] => 31231
)
)

Your problem is in this line:
$result[] = $rvalue;
Consider the case where you only have one item; this will result in:
Array
(
[0] => Array
(
[id] => 2
[brokerid] => 2
[agentid] => 3
[addedby] => 1
[get_agent_details] => Array
(
[id] => 1
[name] => Chesney Hawkes
[ic] => 932132923
[phone] => 2313123
)
)
)
But to be consistent, you need get_agent_details to be a list of items, that happens to have one entry:
Array
(
[0] => Array
(
[id] => 2
[brokerid] => 2
[agentid] => 3
[addedby] => 1
[get_agent_details] => Array
(
[0] => Array
(
[id] => 1
[name] => Chesney Hawkes
[ic] => 932132923
[phone] => 2313123
)
)
)
)
So you need to re-arrange your data, for instance by writing:
$rvalue['get_agent_details'] = [0 => $rvalue['get_agent_details']];
$result[] = $rvalue;
Then, since get_agent_details will already be a list when you encounter a second matching item, your existing code in the inner loop will do the right thing:
// Add an item to the list
$result[$i]['get_agent_details'][] = $rvalue['get_agent_details'];
