在PHP中模拟命名函数参数,有什么好主意？

function myFunction($name, $age) {
    echo "Hello, " . $name . "! You are " . $age . " years old.";
}

$name = "John";
$age = 30;

myFunction($name, $age);

function myFunction($name, $age) {
    echo "Hello, " . $name . "! You are " . $age . " years old.";
}

$name = "John";
$age = 30;

call_user_func_array('myFunction', array($name, $age));

$name = "John";
$age = 30;

myFunction($name, $age);

function myFunction($name, $age) {
    echo "Hello, " . $name . "! You are " . $age . " years old.";
}
