Comments in PHP code are ignored by the ______.

Comments in PHP code are ignored by the PHP interpreter. This means that they don't affect the execution of the code, and they are not sent to the client's web browser. They are solely for the benefit of people reading the code. Comments can be used to explain what your code does, why it does it, and anything else that might be helpful to know. The other options, user, web browser, and web server, all see the results of the PHP code after it has been interpreted, but they don't see the comments.
