As Ben pointed out, missing $ from [$x] in $files[x], but that's just 
your usual broken code.

for ( $x=0; $x <= $number; $x++ )
  if ( $files[$x] != "." && $files[$x] != ".." )
    $master[$lo++] = $files[$x];

The line:

$master[$lo++] = $files[$x];

does the following:

First it assigns the value of $files[$x] to $master[$lo]
Then it increments $lo by 1

And as Ben pointed out, it's possible that the following will work too:

for ( $x=0; $x <= $number; $x++ )
  if ( $files[$x] != "." && $files[$x] != ".." )
    $master[] = $files[$x];

As it just increments the numeric index of $master by 1 each time it 
assigns another element.
