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 .= '<tr>'; }
$o .= "<td>{$file_list[$i]}</td>";
if ( $i % $columns == $columns - 1 ) { $o .= '</tr>'; }
}
// 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( "<td> </td>", $columns - ( $array_count %
$columns ) ) . "</tr>";
}
