I have a possible client looking to do these things with a virutal hosting account:
- disable errors to browser output
- redirect the error_log to a file in my own space
- be able to include functions that are in a subfolder in my own space
- want to increase the filesize of uploaded items
Is this possible somehow, through .htaccess or something?
take a look in the configuration section of the php documentation found at php.net. there are ways to do it both from the httpd.conf file and individual .htaccess files depending on your setup (engine has to be on for .htaccess).
