Answer 1

如果是 cossociative array

function isAssoc($array) {
    $array = array_keys($array);
    return ($array !== array_keys($array));
}

if (isAssoc($ONEANSWER['answers']['answer'])) {
    $ONEANSWER['answers']['answer'] = [$ONEANSWER['answers']['answer']];
}
if (isAssoc($THREEANSWERS['answers']['answer'])) {//it's not associative array
    $THREEANSWERS['answers']['answer'] = [$THREEANSWERS['answers']['answer']];
}

使用 isassoc

Answer 2

好的，只需参考即可根据多个注释，“答案”节点在响应json中的格式不同，如果有多个“答案”在多个答案示例中注意到方括号。

设置一个阵列的一个答案使它可以

echo count(array($ONEANSWER['answers']['answer'])); //expect 1 get 1

在生产中工作，我可以检查它是否是阵列，如果不是一个阵列。
