Become a Better PHP Developer

PHP is probably the most popular web development language right now. At least 20 million domains use PHP and it’s the language used on major sites such as Wikipedia and Facebook as well as in some of the world’s biggest open source projects like WordPress and Drupal.

In this article, I’ll share with you ten things I wish I was told when I was just getting started with PHP development, and I’m hoping you’ll be able to learn a thing or two if you’re just taking your first steps into this awesome web development language.

1. Use PHP Core Functions and Classes

If you’re trying to do something that seems fairly common, chances are, there’s already a PHP function or class that you can take advantage of. Always check out the PHP manual before creating your own functions. There’s no need to create a function to remove the white space at the beginning and at the end of a string when you can just use the trim() function. Why build an XML parser for RSS feeds when you can take advantage of PHP’s XML Parser functions (such as xml_parse_into_struct)?

2. Create a Configuration File

Instead of having your database connection settings scattered everywhere, why not just create one master file that contains its settings, and then include it in your PHP scripts? If you need to change details later on, you can do it in one file instead of several files. This is also very useful when you need to use other constants and functions throughout multiple scripts.

Using a config file is a popular web application pattern that makes your code more modular and easier to maintain.

3. Don’t Over-Comment Your Code:

Proper documentation of your code through comments in your scripts is definitely a good practice, but is it really necessary to comment every single line? Probably not. Comment the complicated parts of your source code so that when you revisit it later you’ll quickly remember what’s going, but don’t comment simple things such as your MySQL connection code. Good code is self-explanatory most of the time.

 

4. Keep Favorite Code Snippets Handy

You’ll be coding a lot of the same things throughout your PHP development career, and keeping code snippets always available will help you save a lot of time. There are several apps that can keep and sync your code snippet collection for you, so no matter where you are, you can always have your snippets available. Some apps you can use to corral your code snippets are Snippet, snippely, Code Collector, and Snipplr (web-based).

5. Use a Good Source Editor to Save You Time

Your editor is where you’ll spend the majority of your time, so you want to use something that helps you save time. Syntax highlighting is a must and definitely something you should be looking for as a software feature. Other bonuses include code hinting, code navigation and built-in debugging tools. All of these features can end up saving you massive amounts of time. An example of a source code editor/IDE for PHP is phpDesigner.

Take the time to get familiar with your source code editor’s features by reading the documentation and reading tutorials online. A bit of time investment in this arena can really streamline your coding workflow.

6. Use a MySQL Administration Tool (Like phpMyAdmin)

I know some crazy hard-core developers who like working with MySQL (the popular Database Management System pairing for PHP) via command line, which, to me, is inefficient and just, well, crazy. It’s a good thing to know how to administer your MySQL database using mysqladmin, but afterwards, you should use a graphical user interface like phpMyAdmin to speed up database development and administration.

phpMyAdmin, in particular, is an excellent open source database viewer/manager that allows you to view your MySQL databases graphically so that you don’t have to waste time doing things via the command line. You can quickly build databases and their tables, export your databases into SQL files, run SQL queries, optimize tables, check for issues, create MySQL database users and set up their privileges quickly, and much more. There is a good chance your web host already has phpMyAdmin installed, and if not, it only takes minutes to install.

7. Use a PHP Framework

It took me a really long time to accept the fact that using a web application development/rapid application development framework would help me out. You have a small learning curve in the beginning, and there will be a lot of reading to do to learn how the API of the framework works, but you get amazing productivity and efficiency benefits later. Using a framework forces you to use better web development patterns that you might not be using right now.

Using a PHP framework pays off big time when you have to share your code with others later on or when you have to work together with someone; it gives you a standardized platform for building web applications. I learned the importance of this the hard way when I had to start hiring other developers.

Some popular PHP frameworks are CakePHP, CodeIgniter, symfony, and Zend.

8. Connect with Other PHP Developers

You don’t know it all. And even if you think you do, there are thousands of others out there that know how to do something better than you do. Join a PHP community like PHPDeveloper and interact with others. By connecting with other developers, you’ll learn better ways of doing the things you’re currently doing.
