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