Programmer: I'm getting an "undefined variable" error in my PHP code. Can you help me figure out what's causing this error?
ChatGPT: Sure! An "undefined variable" error in PHP typically occurs when you try to use a variable that hasn't been defined or initialized. To fix this error, you should make sure that you have initialized the variable before trying to use it. You can also try checking the spelling and case of the variable name to make sure it matches the name used in your code.
