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,$b)
{
print "<hr>a = <br>";
print_r($a);
print "<hr>";
print "<hr>b = <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]
