Try using multi-dimensional arrays, something like:
<?php
$items = array(1,2,3,4,5,6,7,8,9,10);
for($i = 1, $random[0] = $items, shuffle($random[0]); $i < 10; $i++) {
/* Initialize each pass with previous array, then randomize */
$random[$i] = $items;
shuffle($random[$i]);
}
$selected = rand(0,10);
echo "There are a total of " . count($random) . " randomly sorted
arrays. Here are the randomly shuffled numbers for array number
$selected.\n";
/* Now you can access each random array */
print_r($random[$selected]);
?>
