sorting random values from a string

Hi
I have a php string like this:
$string = "one two three four five"
I have to sorting the values randomly every time the page are loaded.
So, for example:
first time
"one two three four five"
second time
"three five one four two"
third time
"five four two one three"
....
The number are a images in a folder and I have to sort these images in
a random sequence.
Thanks for suggestions.

$string =3D "one two three four five";
$array =3D explode(' ', $string);
shuffle($array);
$string =3D implode(' ',$string);

$string = "uno.jpg due.jpg tre.gif quattro.gif cinque.jpg";
$array = explode(' ', $string);
shuffle($array);
$string = implode(' ', $array);
echo $string ;
?>

and this not work
if ($handle = opendir('banner/')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$file = $file . " ";
$array = explode(' ', $file);
shuffle($array);
$file = implode(' ', $array);
echo $file;
} }
closedir($handle);

Because a file might have a space in it, and it might be a directory? It=
's =

quite nonsense to keep juggling between an array & a string.
=

if ($handle =3D opendir('banner/')) {
$files =3D array();
while (false !== ($file =3D readdir($handle))) {
if (is_file($file)) $files[] =3D $file;
}
shuffle($files);
echo implode(' ',$files);
closedir($handle);
}
?>

Re: sorting random values from a string

Sorry Rik but this code not display nothing in my page
(in the directory banner I have some file)

if ($handle = opendir('banner/')) {
$files = array();
while (false !== ($file = readdir($handle))) {
if (is_file($file)) $files[] = $file;
}
shuffle($files);
echo implode(' ',$files);
closedir($handle);}

?>

Nope, I did :P

$dir =3D './banner';
if ($handle =3D opendir($dir)) {
$files =3D array();
while (false !== ($file =3D readdir($handle))) {
if (is_file($dir.'/'.$file)) $files[] =3D $file;
}
shuffle($files);
echo implode(' ',$files);
closedir($handle);}

?>
