Question

Sorry for the beginners question.
I’ve searched for an hour now, and can only find info on adding 1 key => value inside the while loop.
I’m aiming for this result. Thanks

$menu = array(  
    '1' => array('id' => 1, 'parentid' => 0, 'title' => 'Apple'),  
    '2' => array('id' => 2, 'parentid' => 0, 'title' => 'Banana'),  
    '3' => array('id' => 3, 'parentid' => 0, 'title' => 'Tangerine'),  
    '4' => array('id' => 4, 'parentid' => 3, 'title' => 'Pear')
);

I’ve tried a number of things but this seems to be the closest.

$menu = array();
while($row = mysql_fetch_array($query)) {
    $menu[] = $row['id'] ;
    $menu[] = $row['parentid'] ;
    $menu[] = $row['title'];
}

Answer 1

Ahh, looks like you want something like

$menu = array();
while ($row = mysql_fetch_array($query)) {
    $menu[] = array(
        "id" => $row['id'], 
        "parentid" => $row['parentid'], 
        "title" => $row['title']
    );
}

Associative array keys are created using "key" => "value".

Edit

Off topic a bit, but I’d strongly recommend learning PDO for your queries. It’s really easy to learn and has a ton of strong points – security and flexibility being the most important – and really takes your scripts to the next level.
