PHP is a widely used server-side scripting language, so a PHP developer has responsibilities based around developing the back-end of websites and web applications. Having some knowledge of front-end work is also necessary, as you provide support to front-end developers by implementing their changes in the applications. Your duties then include connecting these applications to web services so that they are viewable on the internet. You work with a company’s databases by connecting them to PHP, maintaining them, updating them, and ensuring everything continues to run correctly and efficiently. Databases are useful not only for data querying but also for adding common features, like search boxes, to websites. You may also be required to solve complex issues for developing and integrating data storage.
