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.
