What are the potential pitfalls of using object operators in PHP?

One potential pitfall of using object operators in PHP is that it can lead to fatal errors if the object being accessed is null or not set. To avoid this issue, you can use the null coalescing operator (??) to check if the object is set before trying to access its properties or methods.

// Potential pitfall: accessing object properties without checking if object is set
if ($object->property) {
    // do something
}

// Fix using null coalescing operator
if ($object->property ?? null) {
    // do something
}
