$dirh = opendir ($start);
if ($dirh===false)
{
// handle error and return or exit
}

while (true)
{

$nextfile = readdir ($dirh);
if ($nextfile===false) break;

if ($nextfile=='.' || $nextfile=='..') continue;

// Treat nextfile

}

Much easier. Notice how the braces don't get more than one deep
(instead of three).
