Getting Started with PHP: How PHP Disseminates Information

Chopping Down that Data Tree...

PHP is a programming language that collects data stored in a virtual database from users and outputs it in your browser. Web developers use PHP to create dynamic and responsive websites that are easier to maintain and capable of executing complex tasks.




How does a web browser interpret data using PHP?

This is a map of how PHP interprets and uses data. The user's input is stored in an SQL server, and PHP tells the browser what to do with the information and how it should appear on-screen.

Here, the power, utility and simplicity of PHP in a website is easily demonstrated. Developers use it to create forms, handle user queries such as email correspondence, and most popular today, to retrieve files to compile a website. These techniques are used to build websites in Wordpress to provide users with an easily accessible interface and custom widgets.

You don't need an in-depth understanding of PHP to develop sites with Wordpress, but it helps to know the basics of how it interacts with your website.

This is the first post in the beginning of a series on working with PHP, which will cover the basics including: arrays, variables, loops, objects, calling files, and editing a website while integrating PHP with XHTML, one of the niftiest features of working with this programming language.

Advantages of Working with PHP

Unlike Javascript or Python, PHP can be easily integrated into existing XHTML in a webpage. This is the biggest advantage for web developers. After setting up a database, you can start scripting commands on how to handle user data and styling your page at the same time. As you can see in the map above, you can write HTML outside of PHP commands, placing scripts inside of divs and paragraphs.

This is how web pages are built in Wordpress using the theme concept, allowing developers to create their own designs and sell them online. You can also eventually learn to make your own secure forms and log-ins, a useful tool for any developer to have under their belt.

While all of this may seem daunting to a novice, I plan on trying to make things as simple and readable as possible. Stay tuned for updates, where we'll get started talking about variables and loops.
