What are the best practices for manipulating objects within arrays in PHP to ensure changes are reflected outside of the function scope?

When manipulating objects within arrays in PHP, it's important to pass objects by reference to ensure changes are reflected outside of the function scope. This can be achieved by using the "&" symbol when passing the object as a parameter to the function. By passing objects by reference, any changes made to the object within the function will be reflected in the original array. 

function manipulateObject(&$array) {
    $array[0]->property = 'new value';
}

$objects = [new stdClass()];
manipulateObject($objects);

echo $objects[0]->property; // Output: new value
