Not too long ago, Jeffrey wrote an excellent article on resources to get you started with jQuery. Now its time to give some love back to the server side, and become more familiar with PHP.
PHP is a scripting language that is perfect for developing dynamic web pages and applications. You may be a PHP ninja, or perhaps you don't even know what PHP stands for. However, if you plan on or are involved in any kind of web development, you are bound to run into this fantastic and easy to learn web language. Today we will review 25 resources to get you started with PHP.
So what the heck is PHP?
Straight from the manual, PHP is "a general-purpose scripting language that is especially suited for web development and can be embedded into HTML." PHP is a server side scripting language, meaning all data is interpreted and sent to the browser before the web page is loaded. This is the exact opposite of Javascript, which we call a client side language. All you need to keep in mind is that PHP is a web language that operates and runs on the server side. Next we will study the advantages of PHP and basic syntax before diving into to various resources.
What are some advantages of using PHP?
Every web language comes with its advantages and disadvantages, and you will find PHP is no different. However, PHP is a popular web language for many reasons.
Easy learning curve. The less time you have to spend searching the manual and studying a web language, the more time you will have to actually create and optimize your application. One of PHP's best features is that it is extremely easy to learn compared to other web languages. The syntax is arguably logical and many of the common functions describe exactly what they do.
Familiar syntax. PHP is a great language for developers with programming experience, especially programming in C and Perl, which is what PHP's syntax is mostly based on. If you know how to program in C and/or Perl, you wont have any issues writing applications in PHP.
Cost. It's free and open source. Can't beat that.
Performance.PHP is a relatively efficient web language. Scalability in your code and applications is very important and you can rely on PHP to serve as many web pages as you need efficiently (of course, it can't help if your coding inefficiently).
Community. The PHP community absolutely rocks. You'll find some of the most in-depth and comprehensive documentation of the entire language at php.net. In addition, there are thousands of PHP help forums and websites to help you when you get stuck. Furthermore, since PHP is open source, it is constantly being improved. PHP 5 recently implemented very strong support for object oriented programming and the language continues to become more powerful.
Overview of the syntax
In case you have been living under a rock and have never seen a PHP script, here is a very basic example of how PHP is written.

<?php echo "Your first php script!"; ?> |
A few things to note. Notice the opening tags start with <?php and end with ?>. You may see some developers leave off the 'php' after the question mark. This is called using PHP short tags and is considered bad practice, always use full php tags. You will also notice that the line ends with a semi colon, if it does not PHP will throw an error. Now lets move on to some resources to get you started.
Step 1. Download PHP and learn the fundamentals.
First things first, we need to download the latest version of PHP and install it so we can work with it locally.
