What are best practices for accessing methods and properties using "->" in PHP?

When accessing methods and properties in PHP using "->", it is important to ensure that the object being accessed is not null or undefined to avoid errors. It is also good practice to check if the method or property exists before trying to access it to prevent potential issues. Additionally, using "->" to access methods and properties allows for object-oriented programming and encapsulation in PHP. 

// Check if the object is not null before accessing its method or property
if ($object !== null) {
    // Check if the method exists before calling it
    if (method_exists($object, 'methodName')) {
        $object->methodName();
    }

    // Check if the property exists before accessing it
    if (property_exists($object, 'propertyName')) {
        $value = $object->propertyName;
    }
}
