What are some common pitfalls when working with objects in PHP?

One common pitfall when working with objects in PHP is not properly checking if an object property exists before trying to access it. This can lead to errors if the property does not exist, causing a fatal error. To avoid this, always use the isset() function to check if a property exists before trying to access it. 

// Check if a property exists before accessing it
if (isset($object->property)) {
    // Access the property
    $value = $object->property;
    echo $value;
} else {
    echo "Property does not exist";
}
