Work from home PHP developers create applications, websites, and programs using the PHP programming language. Instead of working in the office, work from home PHP developers complete their tasks outside of the office, either from home or another remote location with internet accessibility. As a PHP developer, your job duties include determining the needs of your client, draw up plans to outline the website or application, then develop the program to your client's specifications. You may also test the core databases and product software to ensure they run smoothly. Once your client has implemented the software, you may be responsible for troubleshooting issues that arise and develop new solutions to complement the original application.
