How to use php

who can teach me please tell me how about to use php in this host

buy a book

There are lots of tutorials in this forum
Please go through it.
U can find many

Here are some useful sites:

http://www.hotscripts.com/index.html
http://www.dynamicdrive.com/
http://www.scriptsearch.com/
http://www.netmechanic.com/cobrands/zd_dev/
http://www.w3schools.com/

dynamic drive doesn't provide PHP scripts or help.

Buying a book is useless, I know a little bit of PHP and released 15 PHP websites without very many problems.

Bizhat.com does not allow PHP.

Nice links. helped me a lot :D

I recommend the book "php,apache mysql web development book from wrox.
Book is useful if you have no previous prgramming knowledge.
