What are best practices for handling object referencing in PHP programming?

When handling object referencing in PHP programming, it is important to be mindful of passing objects by reference to avoid unexpected behavior. To ensure proper handling of object references, use the "&" symbol when assigning objects to variables or passing them as arguments to functions. 

// Create an object
$object = new stdClass();

// Assign the object by reference to a variable
$reference = &$object;

// Pass the object by reference to a function
function modifyObject(&$obj) {
    $obj->property = 'value';
}

// Call the function to modify the object
modifyObject($object);

// Access the modified property
echo $reference->property; // Output: value
