Are there any specific guidelines for handling object manipulation in PHP functions?

When manipulating objects in PHP functions, it is important to pass objects by reference if you want to modify the original object within the function. This can be achieved by using the "&" symbol before the parameter name in the function declaration. By passing objects by reference, any changes made to the object within the function will be reflected in the original object outside of the function. 

// Example of passing object by reference in a PHP function
class Example {
    public $value;

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

function manipulateObject(Example &$obj) {
    $obj->value = "Modified value";
}

$exampleObj = new Example("Original value");
manipulateObject($exampleObj);

echo $exampleObj->value; // Output: Modified value
