使用PHP计数器，并希望使用3的倍数

Question

I've got this code here

<?php
$COUNT = 0;
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
    if ($entry != "." && $entry != ".." & $count % 3 == 0) {
        echo "<td><a href='$entry'>$entry</a></td>";
        echo $Count;
        $Count++;

    }
    else {echo "<tr><td><a href='$entry'>$entry</a></td><tr>";
    echo $Count;
    $Count++;
    }
}
closedir($handle);
}
?>

and I just can't seem to get it to work. I want a new table row every time the counter is a mutiple of 3.

You call $COUNT, $Count, and $count in your script like they are the same variable. They are not. PHP variables are case sensitive. Change them all to $count and it should work.

If you turn error_reporting on so it reports notices, as you should always do in development, you would have caught this quickly.
