What are the limitations of using func_get_args() for handling variable parameters in PHP?

Using func_get_args() for handling variable parameters in PHP can be limiting because it requires manually parsing the arguments array, which can be error-prone and difficult to maintain. Instead, a more robust and flexible approach is to use the splat operator (...) introduced in PHP 5.6, which allows for unpacking an array of arguments into a function call. 

function exampleFunction(...$args) {
    foreach ($args as $arg) {
        echo $arg . " ";
    }
}

exampleFunction('apple', 'banana', 'orange');
