PHP, which stands for Hypertext Preprocessor, is a scripting language that is used to enhance web pages. It enables functions such as creating usernames and passwords, forums, and other necessary parts of the user experience.

How PHP—and other scripting languages—differ from programming languages lies in their execution: the former uses an interpreter to convert its language into machine code, while the latter uses a compiler to do so. This allows Web Developers to create dynamic sites that interact with databases, as opposed to the slower-loading sites that use Common Gateway Interface technology.

This particular scripting language is important to learn because it’s open-source, which makes it easily accessible and free. This means Web Developers skilled in PHP can provide efficient and cost-effective services to employers and clients while increasing their own value—according to Glassdoor, PHP Developers in the U.S. make an average of $81,428 per year.

With its budget-friendliness, flexibility, and fast load times, PHP is a much-needed skill for employers in need of a custom coding project—especially when you consider that slow-loading websites cost retailers $2.6 billion in lost sales each year. Even when business choose to go the WordPress route, custom plugins and technical support are made possible at the hands of PHP Programmers and Developers.

When it comes to actual opportunities for PHP learners, successful ones can count on landing roles such as Web Communications Specialist, Product Lead, UX Designer, Web Developer, Digital Analytics Specialist, Content Writer, Design Director, WordPress Developer, Web Strategist, UI Developer, Digital Designer, Front-end Developer, and various others that are related.

PHP courses offered through Coursera equip learners with knowledge in the basic structure of a web application; the request/response cycle; Hypertext Markup Language; PHP syntax and data structures; how to connect to a MySQL through PHP; how PHP uses cookies and manages session data; and more.

Lessons on PHP are taught by instructors from major universities, including the University of Michigan. Learners can enjoy exploring PHP with instructors specializing in Information, Programming, and other disciplines. Course content on PHP is delivered via video lectures, readings, quizzes, and other types of assignments.
