How can proper object initialization and method invocation prevent undefined property errors in PHP?
Proper object initialization involves creating an instance of a class before accessing its properties or methods. This ensures that the object exists and prevents undefined property errors. Method invocation should also be done on valid objects to avoid errors. By following these practices, you can prevent undefined property errors in PHP.
class MyClass {
public $property;
public function myMethod() {
// do something
}
}
// Proper object initialization
$obj = new MyClass();
// Accessing property after initialization
$obj->property = 'value';
// Calling method on the object
$obj->myMethod();
