I got the answer first of all fatch the data from js file $data = file_get_contents("./data.js");

Create a substring which contain the data from starting "[" to the ending "]"
$substrdata = substr($data, strpos($data,'[')+1, strpos($data,']') - strpos($data,'['));

then replase "\" with space
$substrdata = str_replace("\"", "", $substrdata);

then replace the singal cotes
$substrdata = str_replace("'", "", $substrdata);

and the explode it in the bases of comma and store it in array 
$arr=explode(",",$substrdata);
$json_response = array();

for($i=0;$i<count($arr);$i++)
{
    $row_array['student'] = preg_replace("/\//",'',$arr[$i]);
    array_push($json_response,$row_array);
}

and finally encode in json form $output = json_encode(array('student_info'=>$json_response)); echo $output;
