What debugging techniques can be employed to troubleshoot issues with passing variables to object methods in PHP?

One common debugging technique to troubleshoot issues with passing variables to object methods in PHP is to check if the variable is being properly passed to the method. You can do this by using var_dump() or echo statements to print out the variable before and after it is passed to the method. Additionally, ensure that the method is correctly defined to accept the variable as a parameter. 

class MyClass {
    public function myMethod($variable) {
        var_dump($variable); // Check if the variable is being passed correctly
        // Your method logic here
    }
}

$myObject = new MyClass();
$myVariable = "Hello World";
$myObject->myMethod($myVariable);
