[PHP] Re: Having trouble formatting width using printf() and default spaces

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?

I tried your method and it's a nice variation, though it leaves me with
two issues:
1. I'd like the numbers to be right-aligned.
2. I'd still like to understand why the default padding of spaces isn't
working for printf(). If I could get printf() to pad with spaces, it
would be exactly what I'm after.

Don't forget if you are looking at the output in a browser, the browser
will ignore extraneous white space unless you either surround the text with
PRE tags or use nbsp; instead of a 'standard' spcae character.
