# Write Cleaner Code with Nullsafe Operator in PHP 8!

**[PHP Dev](https://daily.dev/sources/phpdev)** · [@erhanurgun](https://daily.dev/erhanurgun) · 2 min read · 65 upvotes · 12 comments

## Summary

PHP 8 introduces the Nullsafe Operator (`?->`) to simplify code by handling `null` checks within object chains in a single line. Using this operator leads to cleaner, more maintainable, and modern PHP code by eliminating nested `if` statements, resulting in fewer lines of code and faster development.

## Content

Keeping PHP versions up-to-date provides us with significant advantages in both performance and readability in our projects. In the past, we used to get bogged down in endless `if` blocks just to check whether a value existed. For example:

```php
if ($user !== null) {
    $profile = $user->profile; // Eloquent relationship
    if ($profile !== null) {
        $address = $profile->address;
        if ($address !== null) {
            $city = $address->city;
        }
    }
}
```

The **Nullsafe Operator** (`?->`), introduced in PHP 8, now offers us a cleaner and more comprehensible way to write our code:

```php
$city = $user?->profile?->address?->city;
```

With this feature, you can now check objects in a single line while automatically handling `null` checks at every step. Be sure to try it out to eliminate nested `if` statements in your code and achieve a cleaner appearance.

**Why should you use it?**
- Fewer lines, more understandable code
- Faster maintenance and development
- Automatic `null` checking

By using the `?->` operator in your own projects, you can achieve **cleaner, easier-to-maintain, and more modern** PHP code!

> This seriously is soo nice and easy to write/read. This paired with guard clauses when necessary removes soo much indentations :-)

> My experiences:
>
> In this example you can use null coalescing operator like:
> ```
> $city = $user->profile->address->city ?? null;
> ```
> The only difference is that in this way if the `$user` is undefined then `$city` also will be null.
>
> Null coalescing operator is available since 7.4. It works for property access only. For method access only null safety works which is a nice feature.
