If you are going to be displaying certain things depending on what a user chooses, I would create your form with PHP, using if statements to decide what to display and what not to display.

If you want to change the available options in select #2 when you select something in select #1, then what you are looking for is Javascript and not PHP. If you want to filter from the same options in select #2 for every option in select #1 (that is, the options to be displayed in select #2 are always a subset of all possible options in select #2), then pure Javascript would do. If you just have few different options in select #2, then you could hard code this in HTML/Javascript. If you need more options and flexibility, then you could bring PHP into the picture by firing AJAX requests to your web server when a user chooses an option in select #1. You could always cache this in Javascript if you think there is a chance that people will be making many changes (although this is overkill in most situations).
