How can thorough testing and debugging practices help identify errors in PHP code related to method calls on objects?

Thorough testing and debugging practices can help identify errors in PHP code related to method calls on objects by systematically testing different scenarios, checking for edge cases, and using debugging tools to track down issues. By thoroughly testing the code and debugging any errors that arise, developers can ensure that method calls on objects are functioning correctly and producing the expected results.

class MyClass {
    public function myMethod() {
        return "Hello, World!";
    }
}

// Create an instance of the class
$object = new MyClass();

// Call the method on the object
$result = $object->myMethod();

// Check if the result is correct
if ($result === "Hello, World!") {
    echo "Method call on object successful!";
} else {
    echo "Error: Method call on object failed!";
}
