Question

我正在尝试生成一组随机卡但我不想重复，所以我使用randWithout来散发已生成的数字。但是我得到一个 Parse错误：语法错误，意外的T_VARIABLE，期待'（'在$ which_card行，我做错了什么？

 $exceptions = array();

 $which_card = $this->randWithout(0,count($Card_array['Suits']-1), array $exceptions);

排除功能

function randWithout($from, $to, array $exceptions) {
    sort($exceptions); // lets us use break; in the foreach reliably
    $number = mt_rand($from, $to - count($exceptions)); // or mt_rand()
    foreach ($exceptions as $exception) {
        if ($number >= $exception) {
            $number++; // make up for the gap
        } else /*if ($number < $exception)*/ {
            break;
        }
    }
    return $number;
}

Answer 1

$this->randWithout(0,count($Card_array['Suits']-1), array $exceptions);
                                                    ^---- this is causing it

您无需在函数调用

中指定变量保存数组

Answer 2

$which_card = $this->randWithout(0,count($Card_array['Suits'])-1, $exceptions)

如何从函数中删除“数组”并将-1移至计数外？我同意这似乎有点可疑

函数调用时出现意外的T_VARTIABLE
