	      o "
" (ASCII
		10 ( 0x0A)), a new line (line feed).

" (ASCII
		13 ( 0x0D)), a carriage return.

	      o "" (ASCII
		0 ( 0x00)), the NUL-byte.

	      $text = "		These are a few words :) ...  ";
	      $binary = "x09Example stringx0A";
	      $hello  = "Hello World";
	      var_dump($text, $binary, $hello);

	      print "
";

	      $trimmed = ltrim($text);
	      var_dump($trimmed);

	      $trimmed = ltrim($text, " 	.");
	      var_dump($trimmed);

	      $trimmed = ltrim($hello, "Hdle");
	      var_dump($trimmed);

	      // trim the ASCII control characters at the beginning of $binary
	      // (from 0 to 31 inclusive)
	      $clean = ltrim($binary, "x00..x1F");
	      var_dump($clean);
