I have an array laid out like this:

Filelist {
	Filename { "Test.jpg", "Image.jpg" }
	Date { "2009 08 18 00 36 36", "2009 08 25 23 10 04" }
	Ext { "jpg", "jpg" }
}

There are 10 different arrays inside the array "Filelist" which each are a different type of data. I need to sort the Date array, but arrange all other arrays afterwards, so that "Test.jpg" was created on "2009 08 18 00 36 36" even after the Date array was sorted.

I've looked through many pages on the PHP manual, searched the forum, searched google. Tried many things, but I am giving up after a few hours. I guess nobody stores data like I do. I should use objects, but it's too late now. Does anyone have any ideas? My brain can't comprehend what should be done...


To make it easier for someone to help me with this, I made a script with the very basics of my array format. It has the code you can copy/paste on the bottom, and the results on top.

array_multisort should do the job:
http://us3.php.net/manual/en/functio...-multisort.php

PHP Code:

array_multisort($date, $filename, $ext); 


The function assumes that the first array is the one to be sorted. I imagine using objects would still be more efficient.

EDIT:

I just noticed that the dates won't sort the way you want them to if you sort them as strings. You'll need to convert them to a timestamp or some other numeric form and use that array to sort the other items:

PHP Code:

function toTimestamp($strDate)
{
     //convert your string date to a timestamp
}

$timestamps = array_map('toTimestamp', $date);
array_multisort($timestamps, $date, $filename, $ext); 


Oh I think I understand now, it will sort the first array, and then the following arrays will be organized in the same way? It seems to work now. This will do

Thanks

The full "sort":

PHP Code:

array_multisort($filelist["ActualDate"], SORT_DESC, $filelist["Filename"], $filelist["Programname"], $filelist["Extension"], $filelist["Date"], $filelist["Time"], $filelist["Size"], $filelist["URL"], $filelist["Thumb"], $filelist["Download"]); 


ActualDate is the timestamp you mentioned date("YmdHis", $Date) (YYYYMMDDHHMMSS)
