Where to start with PHP?

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

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.
