PHP函数如何接收数组参数？

function my_function(array $array_parameter): void{    // 函数体}

$my_array = ['foo', 'bar', 'baz'];my_function($my_array);

function sum_array(array $numbers): int{    $total = 0;    foreach ($numbers as $number) {        $total += $number;    }    return $total;}// 调用函数$numbers = [1, 2, 3, 4, 5];$result = sum_array($numbers);echo "The sum of the array is: $result";
