php_self error

Hi,

when I run the below code I get a strange output, here is the code:

PATH_INFO <?php echo $PATH_INFO ?><br>
PHP_SELF <?php echo $PHP_SELF ?>

PATH_INFO /phpBB/images/smiles
PHP_SELF /phpBB/images/smiles/a.php/phpBB/images/smiles

why does does php_info gets written atthe end of php_self ??

I cant get any thing with php_self to run.

my sys tem is Win98SE + PHP4.0 + Xitami Server

Thanks
