MY PHP CODE
<?php
include '../config/config.php';
if(isset($_GET['sub_cat_id']))
{
$sub_cat_id = $_GET['sub_cat_id'];
$result = mysql_query("select * from $questions where sub_cat='$sub_cat_id' order by level_fk asc");
$json_response = array(); //Create an array
$i=1;
while ($row = mysql_fetch_array($result))
{
$row_array['qus_pk'] = $row['qus_pk'];
$row_array['question'] = $row['question'];
$qus_pk = $row['qus_pk'];
$option_qry = mysql_query("select * from $qus_ans where qus_pk=$qus_pk");
while ($opt_fet = mysql_fetch_array($option_qry))
{
$row_array['options'] = $opt_fet['options'];
$row_array['right_ans'] = $opt_fet['right_ans'];
array_push($json_response,$row_array); //push the values in the array
}
$i++;
}
echo json_encode($json_response);
}
?>
Und ich mein Ergebnis zu schaffen, bin immer json Antwort wie die folgende
[
{
"qus_pk": "1",
"question": "Ten years ago, P was half of Q in age. If the ratio of their present ages is 3:4, what will be the total of their present ages?",
"options": "45",
"right_ans": "0"
},
{
"qus_pk": "1",
"question": "Ten years ago, P was half of Q in age. If the ratio of their present ages is 3:4, what will be the total of their present ages?",
"options": "40",
"right_ans": "0"
},
