It doesn't like the comma inside the curlies.

If I put this wikitext line somewhere in the page

   <space>1234567889

(so the 9 is "10 characters in") none of these matches:

   $SomeNumber = 4;
   if (preg_match("!^ .{$SomeNumber}!", $_POST['text'])) { ... }
   if (preg_match("!^ .{$SomeNumber},!", $_POST['text'])) { ... }
   if (preg_match("!^ .{$SomeNumber}!s", $_POST['text'])) { ... }
   if (preg_match("!^ .{$SomeNumber}!,s", $_POST['text'])) { ... }
