As a PHP programmer, your job is to develop software for use with a specific operating system, such as Windows or Linux. As you code the program, you may publish it to the web, convert it to another language, or integrate it with existing software. You can expect to spend some time designing, building, testing, and debugging the applications you create. Most PHP work is focused on web-based applications and requires additional coding in HTML as well as the use of database packages like Oracle and MySQL. Your duties also include keeping up-to-date with the latest changes and recommendations for programming.
