Answer 1

Just like what I've said in the comments. Query, fetch, create array structure, then encode:

// connect
$db = new PDO('mysql:host=localhost;dbname=database_name', 'username', 'password');
$member_id = 135; // values
$subcat_id = 3;
// statement
$stmt = $db->prepare('SELECT * FROM db_special WHERE member_id = :member_id AND subcat_id = :subcat_id');
$stmt->execute(array(
    ':member_id' => $member_id,
    ':subcat_id' => $subcat_id
));
// initialize container format
$data = array(
    'member_id' => $member_id,
    'subcat_id' => $subcat_id,
    'special_image' => array(), // initialize
);
// fetch values and push into container with format
foreach($stmt->fetchAll(PDO::FETCH_ASSOC) as $row) {
    $data['special_image'][] = array('image' => $row['image'], 'comment' => $row['comment']);
}
// encode
echo json_encode($data);

Try this hope it will help you.

<?php
//Your Query
$sql = "YOUR QUERY"
$result = mysql_query($sql);

//Your Array
$newArray = array();

//Your Array Data
while($row = mysql_fetch_array($result)){ 
  $newArray[] = "\"".$row['COLUMN NAME']."\"";
}
?>
