Hai, coba ini,
<?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");
$json_response = array(); //Create an array
while ($row = mysql_fetch_array($result))
{
$row_array = array();
$row_array['qus_pk'] = $row['qus_pk'];
$row_array['question'] = $row['question'];
$row_array['answers'] = array();
$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['answers'][] = array(
'options' => $opt_fet['options'],
'right_ans' => $opt_fet['right_ans'],
);
}
array_push($json_response, $row_array); //push the values in the array
}
echo json_encode($json_response);
}
?>
