无法解码json字符串

Question

我有一个json字符串，我想解析小对象的数组，我使用解码器，但它不会帮助，为什么这是幸福吗？

我已定义的变量为$ 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 
}, 

这是怎么我试过

$ arrayOfEmails = json_decode（$ cleanforcharacters）;

，这就是我现在越来越

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

剩下的就是不出来或者

Answer 1

这是因为你已宣布为对象，按键被覆盖的值，而不是设置为新的值： -

你给了： -

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。
