How can PHP developers ensure that classes are properly instantiated and utilized to avoid common errors such as "Call to a member function on a non-object"?

To avoid the "Call to a member function on a non-object" error in PHP, developers should ensure that classes are properly instantiated before calling their methods. This error typically occurs when trying to access a method on an object that has not been correctly instantiated. To prevent this error, always check if an object is valid before calling its methods. 

// Example code snippet to demonstrate proper instantiation of a class

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

// Instantiate the class and check if it is a valid object
$myObject = new MyClass();

if ($myObject instanceof MyClass) {
    echo $myObject->myMethod();
} else {
    echo "Error: Object not properly instantiated.";
}
