I use localhost to test my connection between google chrome and php. When there’s some error, the browser would show the exact file name of the php file, including the absolute path in my computer and which line the error happen. (Like: undefined index, (var name), in c:\XXX\yyy.php, Line 3)
Is this some kind of serious security issues ? I’ve set the display_error = off in my php.ini.
Sounds like a problem with your PHP config. Are you sure the ini file you’re editing is actually being loaded? Make sure that it’s in the right location with the right permissions, and maybe restart your web server just for kicks.
You might have better luck in a PHP-specific forum – this has to be an issue other people have had. Not to say you can’t ask for help, here, but it’s not exactly our specialty, you know?
