# Null Safe Operator |
|
|
|
The Null Safe Operator is a handy feature in PHP which deals with an issue that often pops up when working with objects: trying to access properties or methods on an object that might be null. Instead of a fatal error, the PHP Null Safe Operator (indicated by ?->) allows null values to be returned safely, making your code more robust. Here's a quick example, consider $session?->user?->name. If $session or user is null, PHP will stop further execution and simply return null. This makes PHP more resilient when processing unpredictable data. |
