Programmer: I'm getting an error message that says "Call to undefined function" when I try to call a function in my PHP code. What does this mean and how can I fix it?
ChatGPT: This error message typically means that PHP can't find the function you're trying to call. This could be because the function is defined in a different file that hasn't been included, or because the function name is misspelled. To fix this error, you'll need to make sure that the function is defined and that it's being called correctly. You can also check the PHP documentation for the function to make sure you're using it correctly.
