Just a note about this code....
It'll generate lots of non-matching lists. If you want to increase the
match probability, reduce the range on the inner-most mt_rand(). Maybe
like this:
<?php
$lines = mt_rand(10,100);
for ($i = 0; $i < $lines; $i++) {
$entries = mt_rand(10,100);
for ($j = 0; $j < $entries; $j++) {
if ($j > 0) {
echo " ";
}
echo mt_rand(-1 * $entries, $entries);
}
echo "\n";
}
?>
