sort associative arrays

Hallo!

I have an associative array containing dates.

here the code:

$arr = array ("2009-03-11", "2009-06-22", "2007-04-14", "2009-04-14", "2009-04-15");

sort ($arr);

echo "<pre>";
print_r ($arr);
echo "</pre>";

PHP:

It displays

Array
(
    [0] => 2007-04-14
    [1] => 2009-03-11
    [2] => 2009-04-14
    [3] => 2009-04-15
    [4] => 2009-06-22
)

Please help me

Thanx!

 

Are you getting this list from a MySQL database, you can get them sorted there.

You can also use arsort instead of sort.

 

These are things you should just look up on http://php.net - if you found http://php.net/asort you'd find in the related function section that there's also arsort: http://php.net/arsort which will sort an array in reverse order.

 

You could use

$arr = array_reverse(sort($arr));

PHP:

 

Um dude there's already a specific function for this as I said in the previous post, "arsort". There's no need to combine other functions to recreate the same behavior.

 

Well the example isn't an associative array, and it's also using a format for the dates that puts the most significant portion of the date first with a zero-fill in the lessor parts (YYYY-MM-DD), so "sort" or since you want reverse order, "rsort" will work.
