Hey guys, i'm in dare need of PHP-MySQL tutorial also need tutorials on Linux networking, where can i download these tutorials. thanks

Usually you find this things with Google ...

www.google.com

I also have been intending to search for a PHP-MySQL tutorial when I found a spare moment. So I just now I did the obvious simple google search
+PHP +tutorial +MySQL
expecting to post back here the report that it's not that simple (too many false positives to dig through).

But hansalfredche is correct this time. There are lots of hits and at first glance all the top ones look good.

Some of those good looking ones are:

http://www.freewebmasterhelp.com/tutorials/phpmysql
http://www.php-mysql-tutorial.com/
http://www.tizag.com/mysqlTutorial/
http://www.w3schools.com/php/php_mysql_intro.asp
http://php.about.com/
http://www.phpsimple.net/
http://www.phpfreaks.com/tutorials.php
http://blazonry.com/scripting/linksdb/index.php

As for Linux Networking: Sorry I don't have a clear enough idea what you're asking to know the right keywords to do a useful google search. I assume "Linux Networking" would be too general a search.

I can suggest :

Also you can use resources above and in addition php tutorials

You even don't need to download them, you may learn both PHP and MySQL from online tutorials such as php tutorials. Hope you will find it useful.
