Dividing rows into dimensional array - php

Question

I want to get the list for the food from the database into array order by category so that I can split each entry into the categories.
Like this..
$menu = array(
'Appetizers' => array(
'Chicken Tenders' => '$2.99',
'Twisted Chips' => '$1.99'
),
'Seafood' => array(
'Bayou Tilapia' => '$4',
'Grill Atlantic Salmon' => '$3.99'
),
'Steaks & Combos' => array(
'Cowboy Grande Sirloin' => '$7.99'
)
)
Here is what I did.
$db->Query("SELECT menuTitle,menuCategory,menuPrice FROM menu");
$menu = array();
while ($row = $db->Row()) {
$a = array($row->menuCategory => array($row->menuTitle=>$row->menuPrice));
array_push($menu,$a);
}
It doesn't seem to work. Would you please advise how to achieve this?

Answer 1

replace:
$a = array($row->menuCategory => array($row->menuTitle=>$row->menuPrice));
array_push($menu,$a);
with:
$menu[$row->menuCategory][$row->menuTitle]=$row->menuPrice;

Answer 2

The code in the while block is not exactly seeming right, as you always redefine the $a array while iterating.
while ($row = $db->Row()) {
$a[ $row->menuCategory ][ $row->menuTitle] = $row->menuPrice;
array_push($menu,$a);
}
This way, you will only append new keys to the array.

Answer 3

$db->Query("SELECT menuTitle,menuCategory,menuPrice FROM menu");
$menu = array(); $a = array();
while ($row = $db->Row()) {
$a[$row->menuCategory ][$row->menuTitle] = $row->menuPrice;
}
array_push($menu,$a);
echo "<pre>";print_r($menu);echo "</pre>";
