Parsing an array with PHP in a foreach loop - php

Question

I want to parse an array with PHP's foreach loop to get the object names and values inside the 'ques' array.
[
{
"ques": [
{
"name": "comment",
"value": "comment me for the reason",
"sur_id": "1",
"user_id": "admin#gmail.com",
"pagename": "question_response"
},
{
"name": "check-box[]",
"value": "1"
},
{
"name": "radio",
"value": "radio 2"
},
{
"name": "yes",
"value": "no"
}
]
"ques":[
{
"name": "date",
"value": "2015-10-23"
},
{
"name": "select-deopdown",
"value": ""
},
{
"name": "true",
"value": "false"
},
{
"name": "number",
"value": "55"
}
]
}
]
I want to separate the value from the 'ques' array:
while ($fetch = mysql_fetch_array($query1)) {
$content = $fetch['CONTENT_VALUES'];
// print_r($content);
$content_value= mb_convert_encoding($content ,"UTF-8");
$datas = json_decode($content, true);
foreach($datas->ques as $values)
{
echo $values->value . "\n";
print_r($values);
}
$test[] = array('ques' => $datas ,'answer'=>$values);
}
