What are some common pitfalls to avoid when passing arguments to functions in PHP?

One common pitfall to avoid when passing arguments to functions in PHP is not providing the correct number of arguments. This can lead to errors or unexpected behavior in your code. To solve this issue, make sure to always check the number of arguments being passed to a function and handle any missing or extra arguments appropriately. 

function myFunction($arg1, $arg2) {
    if(func_num_args() != 2) {
        throw new Exception('Incorrect number of arguments provided');
    }

    // Rest of the function code
}
