How can the scope of a PHP function be effectively debugged to identify errors?

When debugging the scope of a PHP function, one effective way to identify errors is by using `var_dump()` or `echo` statements to check the values of variables within the function. This can help you understand the flow of the function and pinpoint any issues related to variable scope. Additionally, using a debugger tool like Xdebug can provide detailed information about the execution of the function and help you trace any problems. 

function myFunction() {
    $var1 = 'Hello';
    $var2 = 'World';

    var_dump($var1, $var2); // Check the values of variables

    // Rest of the function code
}
