Does a php programmer required to know javascript?
You CAN get a job, but it will be significantly harder. Your pay grade might also suffer. As a developer myself, I can attest to “More is Better.” The more languages you know, the more versatile you are in the work force. The more versatile you are, the higher the demand will be for you. If you are a web developer I recommend learning the following: CSS, JavaScript, ASP.NET, PHP, and SQL. Those should be the basics for any web developer, however you can opt to specialize in PHP, but make sure you can at least understand the other languages listed.
