$dirh = opendir ($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).
