where is your file db_login?... that is one cause for problems, or alternatively where are the other 3 lines, as PHP is reporting as the inlcude is on iline 13 yet PHP reports the fault on 10
if you are concerned that you installation isnt working then Id suggest you run a simple testscript calling the
phpinfo() function
eg
<?php
phpinfo(-1)
?>
the phpinfo should provide a lot of bumpf, not least of which is the database server the webserver is connected to
Im not sure you webserver is correclty specified
