Question

My table looks like:

id | title | link | kind
------------------------
 1   link1   http   one
 4   link2   http   two
 2   link9   http   one

I want to give back a JSON Array (JSON parsing is not the problem!) which looks like:

one
 - link1, http
 - link9, http
two
 - link2, http

The kind-colum is dynamic so I do not know the actual string. (But it is never (null)!)

What I have:

$links = array();
while($row = mysql_fetch_object($result)) {
    $link = array(
        'title' => $row->title,
        'link' => $row->link,
        'kind' => $row->kind
    );
    $links[] = $link;
}

echo json_encode($links);

That’s one array with all columns for each element.

Answer 1

Use $row->kind as an index into the top level array.

$kinds = array('one' => 1, 'two' => 2, ...etc...);
$links = array();
while($row = mysql_fetch_object($result)) {
    $link = array(
        'title' => $row->title,
        'link' => $row->link
    );
    $links[$kinds[$row->kind]][] = $link;
}

echo json_encode($links);
