json - 无法解码 json 字符串

Question

我有一个要解析为小对象数组的 json 字符串，我正在为此使用解码器，但它无济于事，为什么会这样？

我已将变量定义为 $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）

discount_org: [
{
day: 0,
time: 8,
discount: 10
},
{
day: 0,
time: 14,
discount: 10
},

这就是我尝试的方式

$arrayOfEmails = json_decode($cleanforcharacters);

这就是我现在得到的

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

其余的也没有出来

这是因为您已将其声明为对象，并且键正在覆盖值而不是被设置为新值：-

你已经给了：-

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

它应该是：-

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);

这会给你正确的结果。
