try using usort() instead of uksort() - (i haven't checked the manual but) I
believe uksort is for sorting based on the keys and not the values, which is
what you're trying to do

Subject: [PHP] Sorting Multi-Dimensional Arrays using uksort()
Hey folks:
I have a function that returns an array. I'm assigning the returned array to
a variable inside another function:
--
$dirs = getFileArray($parentDir,title_2.txt);
--
If I use print_r() on the variable it writes out as expected:
--
Array
(
[0] = Array
(
[folderName] = 97StudioPhotos
[linkText] = Studio 3/27 - 3/30 (by Matt Myrdal/VE)
[sortDate] = 03/31/02
)
[1] = Array
(
[folderName] = 98PromoPhotos
[linkText] = Promo Photos BW (by Matt Myrdal - 3/24/02)
[sortDate] = 03/24/02
)
[2] = Array
(
[folderName] = 99PhotoSet1
[linkText] = Photo Set I (by Matt Myrdal - 3/12/02)
[sortDate] = 03/12/02
)
)
--
Now I want to sort this array using a custom defined sort method:
--
uksort($dirs,sortByDateDesc);
function sortByDateDesc($a,$b)
{
print hra = br;
print_r($a);
print hr;
print hrb = br;
print_r($b);
print hr;
print $a. vs .$b.br;
if ($a[sortDate] $b[sortDate]){
print .$a[sortDate]. .$b[sortDate].br;
return -1;
} else if ($a[sortDate] $b[sortDate]){
print .$a[sortDate]. .$b[sortDate].br;
return 1;
} else {
print .$a[sortDate]. = .$b[sortDate].br;
return 0;
}
}
--
As you can see, I've added a bunch of print() calls for testing. The trouble
is that none of the variables are being output into the print functions and
all of the print_r() calls just return 1. In the end, the array is not
being sorted at all. Why can't I access any of the array elements in this
function and why won't it sort correctly?
I've tried accessing the elements everyway I can think of:
$a[sortDate]
$a[sortDate]
$a[2]

Chris Bloom
