无法解码json字符串

我有一个json字符串，我想解析成一个小的对象数组，我正在使用解码器，但它没有帮助，为什么会发生这种情况

我已经将变量定义为$cleanforcharacters

$cleanforcharacters = preg_replace('/["{mtwrdayfsasusseto}"]_/', '', $found['newdiscounthours']);

这是我的输出

discount_org: "{"day":"8:00","time":"12:00","discount":"10","day":"8:00","time":"12:00","discount":"10"}"

这是所需的输出（对象数组）

我就是这样尝试的

$arrayOfEmails=json_decode（$cleanforcharacters）

这就是我现在得到的

discount_org: {
day: "20",
time: "12:00",
discount: "20"
}

---

其余的也不会出现

这是因为您已声明，作为一个对象，键将覆盖这些值，而不是设置为新值：-

你给出了：-

discount_org: "{"day":"8:00","time":"12:00","discount":"10","day":"8:00","time":"12:00","discount":"10"}"

应该是：-

discount_org: "[{"day":"8:00","time":"12:00","discount":"10"},{"day":"8:00","time":"12:00","discount":"10"}]"

然后使用：-

$arrayOfEmails = json_decode($cleanforcharacters,true);

---

这将给出正确的结果。

这不是因为它是字符串而不是对象吗？如果是这样，我认为解码器不能处理字符串

$arrayOfEmails = json_decode($cleanforcharacters,true);
