sorting random values from a string

[pt36]

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

$array = explode(' ', $string);
shuffle($array) ;
$string = implode(' ',$string);

$string = implode(' ',$array);

$array = explode(' ', $string);
shuffle($array) ;
$string = implode(' ', $array);

?>

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

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.

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

}
shuffle($files) ;
echo implode(' ',$files);
closedir($handl e);}

Nope, I did :P

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

?>
