Now that you know how to use some debugging features, try it out a few more times to build up your confidence. Here are some suggestions on what to try out:
Put a breakpoint on the form processing script from example 2 and step through the execution flow. Check it is doing what you expected.
Add a watch on an expression combining several variables, so that you can see observe changes to the whole expression. (Eg,
$x + $y - 10)Try opening the webpage on a computer in your network other than your development computer (localhost). You may need to check your computer's IP address.
