What is the issue with accessing variables in PHP when using the -> operator?

When accessing variables in PHP using the -> operator, the issue arises when trying to access properties of an object that is null. This can result in a "Trying to get property of non-object" error. To solve this issue, you can use the null coalescing operator (??) to check if the object is null before accessing its properties. 

// Example of accessing object properties safely using the null coalescing operator
if ($object->property ?? null) {
    // Access the property safely
    echo $object->property;
} else {
    // Handle the case where the object is null or the property doesn't exist
    echo "Property is null or does not exist";
}
