Re: [PHP] What kind of looping ?
try using $count=0; before the loop (while loop is fine)
then before the end of the loop $count++;
inside the loop if ($count % 4) {
that is where you want it to break and start running the other code
}
so you would have
$table = "";
$counter = 0;
while ($tableset = mysql_fetch_array($result) ) {
$table = "";
if ($counter % 4 == 0) {
$table .= " FILE 0 FILE 1 FILE 2 FILE 3 ";
} else {
$table .= " FILE 4 FILE 5 FILE 6 FILE 7 ";
}
$counter++;
}
$table .= "";
something like that, if this doesnt get the total desired result try playing with the
% 4 == 0 to
like == 1 or 2, see if that gets a desired result. please please this is some psudo
code I threw
together you might need to tweek.

The % (modulus) operator is the key to this type of looping. I didn't test
the code below, but I've done this enough times that I'm pretty sure it's
correct. If not it should be pretty easy to correct after you test it.
$columns = 4;
$array_count = count( $file_list );
for ( $i = 0; $i < $array_count; $i++ )
{
if ( $i % $columns == 0 ) { $o .= ''; }
$o .= "{$file_list[$i]}";
if ( $i % $columns == $columns - 1 ) { $o .= ''; }
}
// Create blank table cells if final row doesn't use all columns.
// You can get away without this on broken browsers like IE, but
// then you'll generate invalid HTML and browsers like NS
// won't display your pages.
if ( $array_count % $columns > 0 )
{
$o .= str_repeat( " ", $columns - ( $array_count %
$columns ) ) . "";
}

Re: [PHP] What kind of looping ?
echo "";
while(list(,$fname) = each($file_list)) {
if(!($cnt % 4) && $cnt++!=0) {
echo "";
}
echo "$fname";
}
echo "";
Didn't actually test that, but it should be close ... the important
piece is ($cnt % 4) ... modulo arithmetic is your friend. That and
thinking in terms of cells, not rows.
