Yeah, this will give you an array of the numbers 1 - 10 in random
order. If you want a different range, change the parameters to suit.
<?php
function rand_array( $start, $finish ) {
srand ( (double) microtime() * 1000000);
$rand_array = range( $start, $finish );
// it really irritates me the way PHP's sort functions mess around
// with the original array rather than returning a sorted array so
// I can assign it to where I want it.
shuffle( $rand_array );
return $rand_array;
}
print_r( rand_array(1, 10) );
?>
