I’m beginner on PHP, So want primary tricks that make me easy to understand.
I’d start with the Getting Started section of the manual
http://us3.php.net/manual/en/getting-started.php
Check the stickies at the top of this forum, especially http://www.sitepoint.com/forums/showthread.php?716526-PHP-Basics
The books on here are good, “PHP & MySQL: Novice to Ninja” is a great place to start.
If you are looking for an introduction to PHP, I suggest checking out Larry Ullman’s PHP 6 and MySQL 5 book.
That book does not only introduce you to PHP, but also covers more advanced topics as well. It’s a great book for beginners and intermediate programmers.
