He's using ASCII??

37 is Line Feed,
13 is Carriage Return, and
21 is New Line
in EBCDIC. And, PHP runs on EBCDIC machines.

Better to use '\r' for Carriage Return, and '\n' for Linefeed / Newline, or
PHP defined constant (iirc, $PHP_EOL), and let PHP decide which platform,
which characterset, and which codepoints to use.

Or, better still, use the proper function (in the OP's case, another call to
imagestring() ) to achieve the proper text alignment.
