Sorting a multi dimensional array

Hi,
I was trying to sort a multi dimensional array ..
e.g

$todo_cats[0]["TodoCat"]["name"] = "Basic Todo";

$todo_cats[0]["TodoTask"][0]["id"] = 1;
$todo_cats[0]["TodoTask"][0]["name"] = "Select a date";
$todo_cats[0]["TodoTask"][0]["position"] = 2;

$todo_cats[0]["TodoTask"][1]["id"] = 2;
$todo_cats[0]["TodoTask"][1]["name"] = "Determine your budget";
$todo_cats[0]["TodoTask"][1]["position"] = 1;

i tried sorting using the code below .. which did not work ..

foreach($todo_cats as $key =>$cat){

foreach($cat["TodoTask"] as $key1 => $row){

$position[$key1] = $row['position'];
}
array_multisort($position, SORT_ASC, $cat["TodoTask"]);
}


Any clue how do i sort it ... ??

 

How do you want to sort it?

 

sort it on the basis of "position" key ...

If you don't mind creating a new array or won't affect your scripting you could sort the array and it's sub arrays individually while passing them into a new array.

Do I make sense.

 

jestep is spot on, usort is the way to go. Here is a useful link for you.
