Question

while($row = mysql_fetch_array($query)){
    $response = array(
        'id' => $row['true'],
        'username' => $row['username'],
        'image'=>$row['image']
    );
    echo json_encode($response);

        }

im trying to send like 20 rows back to a mobile client using json, is this the way to do it, im not sure if this makes sense!! espcially in a while loop.

Answer 1

Create an array and json_encode it after your loop:

$responses = array();
while($row = mysql_fetch_array($query)){
    $response = array(
        'id' => $row['true'],
        'username' => $row['username'],
        'image'=>$row['image']
    );
    $responses[] = $response;
}
echo json_encode($responses);
