Array Manipulation With PHP
Take an in-depth look at PHP's array manipulation tools for faster, more efficient code.

| Knowledge Is Power |

As a PHP developer myself, I spend a fair part of my time looking for ways to write cleaner, more efficient code. I'll be the first to admit that I don't succeed too often; however, that doesn't stop me from making the effort. And nine times out of ten, I don't have to look too far - the PHP community is incredibly generous with its advice and assistance, and the language itself offers tools which can slice through complex problems in much the same way as a hot knife slices through butter.

Nowhere is this clearer than in the case of PHP's built-in functions, which offer developers power and flexibility of the sort not seen in most other languages. Sadly, most developers don't use this power - not because they don't want to, but simply because they're not even aware of the full extent of PHP's capabilities. And this lack of knowledge can often spell the difference between a tight, efficient Web application and a slow, inefficient one.

Over the next few pages, I'm going to illustrate my point by taking an in-depth look at PHP's array manipulation capabilities. If you're like most developers, you probably use arrays extensively in your development activities; however, your knowledge of array manipulation techniques is limited to counting the elements of an array or iterating through key-value pairs.

PHP's array manipulation functions allow you to do much, much more...and this article will open your eyes to the possibilities.

In addition to providing a gentle introduction to PHP programming in general (and PHP array manipulation in particular), this article will offer you a broad overview of PHP's array functions, serving as both a handy reference and a tool to help you write more efficient code. Regardless of whether you're new to PHP or if you've been working with the language for a while, you should find something interesting in here.

Let's get started!


How to do Everything with PHP & MySQL
How to do Everything with PHP & MySQL, the best-selling book by Melonfire, explains how to take full advantage of PHP's built-in support for MySQL and link the results of database queries to Web pages. You'll get full details on PHP programming and MySQL database development, and then you'll learn to use these two cutting-edge technologies together. Easy-to-follow sample applications include a PHP online shopping cart, a MySQL order tracking system, and a PHP/MySQL news publishing system.
