In a grid... like an HTML table? You could something like:
$row = 20;
$col = 5;
echo '<table>';
for ($i = 1; $i < $row; $i++) {
echo '<tr>';
for ($j = 1; $j < $col; $j++) {
echo '<td>'.rand(1, $sides).'</td>';
}
echo '</tr>';
}
echo '</table>';
for ($i = 0; $i < 100; $i++) {
if (!($i % 5)) {
print("<br />");
}
printf("%'.10u", rand(1,$sides));
}
Currently, I'm padding with '.', but I'd like to pad with the default
spaces.
For example, printf("%10u", rand(1,$sides)); Except the numbers end up
like,
7 10 14 19 3
4 6 16 13 2
etc.
Why is it that when I leave out the padding character, the output isn't
padded?
