Arrays and ordering...

[rJonesX]

Imagine I have a parent array...

$parent_array

with two variables that are themselves arrays...

$child_array_1 = $parent_array[0];
$child_array_2 = $parent_array[1];

and each one of those children stores a couple of values, lets say Name, ID number, and Age...

$age = $child_array_1[2]

What I need to accomplish is simple but destroying me - I am a newbie.

I have a basic formula for ordering the individuals by age and printing them out to the screen. Simply loop through picking out the values of the $child_array...[2]'s - compare them against one another and have them placed into an array in ascending order, and then loop through that ordered array, matching each age to the appropriate $child_array_#[3] and then printing out the parent... Make sense?

Well, i know how to extract the data from these arrays using the (xml dom) get_content() method, but once I have all of these values (in this case ages) how do i compare them against one another and then put them into an array in the correct order...

get what im saying? anyone got a better idea?

help plz...

better do it like this

Array[$child_number][0,1,2...{id,parent,age...}]

I can see how I can extract the values to a new array... so now all I need to do is this...

say I have

$array[0] value is 1321243
$array[1] value is 0
$array[2] value is 194328

How do i get it so that they are switched to...

$new_array[0] value is 0
$new_array[1] value is 194328
$new_array[2] valu is 1321243

any ideas? thanks in advance, sorry about the double post...

Well, PHP has half-a-dozen sorting functions...

If a plain old sort() won't do what you want, and you can explain clearly enough to yourself how you want the array entries sorted, you can put that rule into a function for use by usort().
