It's a little cumbersome and probably has way too many loops, but processor time is cheap and memory is even cheaper. I've found PHP's array parsing to be fairly quick.
Alternatively, use the path as the index for your array; i.e:
$array1 = array("path" => array("path_id" => 3,
"year" => 2004,
"month" => "02",
"day" => "05",
"hits" => 3);
When you're parsing your log (which is what I'm assuming you're doing), you would populate $array1 as follows:
$array1 = array();
while (parsing())
{
$array1[$path]['path_id'] = $path_id;
$array1[$path]['year'] = $year;
/** etc... **/
}
$paths = array_keys($array1);
sort($paths);
foreach($paths as $path_to_check)
{
/** Do stuff with $array1[$path_to_check] **/
}

Hi,
I've read and re-read array_multisort(), but still can't get a grip on
how to sort my array:
Array
(
[0] => Array
(
[path_id] => 3
[year] => 2004
[month] => 02
[day] => 05
[hits] => 3
[path] => home
)
[1] => Array
(
[path_id] => 2
[year] => 2004
[month] => 02
[day] => 05
[hits] => 1
[path] => plan
)
[2] => Array
(
[path_id] => 7
[year] => 2004
[month] => 02
[day] => 05
[hits] => 1
[path] => specials
)
)
In this case, I'd like to sort the entire array on [path]. Can anyone
provide some tips or an example to start from?
