I'd like any help anyone can give particularly with PHP, SQL, even advanced HTML.  Also any tips on using Apache Web Server would be good.  I have the following sites for tutorials etc but any more good ones would be appreciated.

for SQL   http://sqlcourse.com/

for PHP  http://php.resourceindex.com/

For a ton of authoring languages, try  http://www.stars.com/Authoring/Languages/
