更改字符串的格式

Hello My question is that i will have a textarea which i want to paste the following

[{"1173627548":{"methv":"dont know","q1":"-","q2":"-","q3":"U","q4":"-","comm":""}},{"1173627548":{"methv":"dont know","q1":"-","q2":"-","q3":"U","q4":"-","comm":""}}]

is there any way i can run a loop which allows me to manipulate the data individually so i can update this to the database. so the first time i run the loop is get this:

{"1173627548":{"methv":"dont know","q1":"-","q2":"-","q3":"U","q4":"-","comm":""}}

if possible i want to strip out the {'s and :'s and "s so i am left with the commas and the data. For example:

1173627548,methv,dont know.. etc

sorry if i am unclear with my question in any way.

$myhugejson = 'blah...';

$array = json_decode($myhugejson, true);

foreach($array as $sub) {
    print_r($sub);

    echo $thing = $sub[0]['methv'];
    echo $second = $sub[0]['q1'];
}

In each iteration, $sub should contain your list.

All of this is assuming you're using JSON, which I think that is.
