How can undefined property errors be avoided when working with objects in PHP?

To avoid undefined property errors when working with objects in PHP, you can use the isset() function to check if a property exists before trying to access it. This helps prevent errors when trying to access properties that have not been set on an object. 

// Check if the property exists before accessing it
if(isset($object->propertyName)) {
    // Access the property if it exists
    $value = $object->propertyName;
    // Use $value as needed
} else {
    // Handle the case where the property is undefined
    echo "Property does not exist";
}
