<？ echo __FILE__。 '>'。 __LINE__。 '<HR>'; ＃==>奇怪的输出

If I use this php code I get really strange output (for me):

<? echo __FILE__ . '>' . __LINE__ . '<hr>';

Result in a web browser:

./sl5/echo_colored.functions.php' . __LINE__ . '

phpinfo() shows the following:

PHP Version 5.3.14<br>
...<br>
cgi.check_shebang_line  0   0<br>
auto_detect_line_endings    0   0<br>
zend_codetracing.trace_source_lines On  On<br>

Any suggestion for fix or workaround this?
