Problems with require.

Im having a problem that im assuming is related to my core PHP code rather than the pear file I am trying to include (though if you folks think I need to look into that, thats ok too). Basically im seeing the following when I try to load my page: Warning: main(DB.php) [function.main]: failed to open stream: No such file or directory in c:\wamp\www\testing\Ch4\test_dbi.php on line 26 Fatal error: main() [function.require]: Failed opening required 'DB.php' (include_path=':c:/wamp/www/PEAR:c:/wamp/www/phplib:c:/wamp/www/testing/ch4/class:.;C:\php5\pear') in c:\wamp\www\testing\Ch4\test_dbi.php on line 26 The line in question is: require_once 'DB.php'; I have added the path to my PEAR directory thru the path command, though when I print out the contents for my $PEAR_DIR variable it shows as : c:/wamp/www/PEAR. Not sure if it matters that the slashes are linux-style or not, but I thought I would point that out. I browsed to the directory and DB.php does exist there and I have even tried hard coding the full path ( i.e. require_once 'c:\wamp\www\PEAR\DB.php' and also with /'s instead of \'s) and it still nets the same errors. Anyone have any idea why this is happening? What power would hell have if those imprisoned here would not be able to dream of heaven?
