Ordering array won't work?

[frizzle]

Hi there,

I want to scan a dir, put the *.gif into an array, and order that (
01.gif, 02.gif etc),
and put that array into a $_session-array. (Session & Headers are
initiated before this code)
I have the code below, everything works, except for the ordering.

Any clues ?

Thanks, Frizzle.

$dir = opendir("./img/");

while( $file = readdir($dir)){
if (preg_match("/\.gif$/", $file)) {

$filename = preg_replace( "/\.gif$/", '', $file );
$_SESSION['all_pics'][$filename] = "Foobar";

};
};

closedir( $dir );

asort( $_SESSION['all_pics'] );

Well, if the value of every array item is the same, offcourse there will be
no sorting done.
If you want to sort on key:
ksort($_SESSION['all_pics']);

Allthough I can't image why:
$_SESSION['all_pics'][] = $filename;
...
asort($_SESSION['all_pics']);
does not do...

All the values in your array are equal to "Foobar", and so asort doesn't need
to do anything to the array to sort it.

Start at http://uk2.php.net/manual/en/ref.array.php

Look at all the various functions with "sort" in their name. You'll find the
one you want soon enough.
