Answer 1

Your string is in json format. To get value from it, you should convert it into an array like this:
$json = '{"status":1,"msg":"1 out of 1 Transactions Fetched Successfully","transaction_details":{"2767712494": {"mihpayid":"268999084","request_id":"","ref_num":"020814301298","amt":"1.00","txnid":"5454355435","additional_charges":"0.00","productinfo":"SHIRT"}}}';
$array = json_decode($json, true);
echo '<pre>'; print_r($array);
Your array will look like this:
Array
(
[status] => 1
[msg] => 1 out of 1 Transactions Fetched Successfully
[transaction_details] => Array
(
[2767712494] => Array
(
[mihpayid] => 268999084
[request_id] =>
[ref_num] => 020814301298
[amt] => 1.00
[txnid] => 5454355435
[additional_charges] => 0.00
[productinfo] => SHIRT
)
)
)
To get msg you should write like this:
echo $array['msg'];
You can get more information from json_decode

Answer 2

This response looks like JSON format.
Pass this response string to php method json_decode like:
$response = json_decode($yourResponseString,true);
and then you should be able to access it's properties like a regular associative array:
$msg = $response['msg'];
