How can PHP developers ensure that objects are properly modified within functions?

PHP developers can ensure that objects are properly modified within functions by passing objects by reference rather than by value. This allows the function to directly modify the original object, ensuring that changes persist outside of the function scope. 

class MyClass {
    public $value;

    public function __construct($value) {
        $this->value = $value;
    }
}

function modifyObject(MyClass &$obj) {
    $obj->value = "Modified value";
}

$obj = new MyClass("Original value");
modifyObject($obj);
echo $obj->value; // Output: Modified value
