無法解碼json字符串

Question

我有一個json字符串，我想解析小對象的數組，我使用解碼器，但它不會幫助，爲什麼這是幸福嗎？

我已定義的變量爲$ cleanforcharacters

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

這是我的輸出

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

這是所需的輸出（對象數組）

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

這是怎麼我試過

$ arrayOfEmails = json_decode（$ cleanforcharacters）;

，這就是我現在越來越

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

剩下的就是不出來或者

Answer 1

這是因爲你已宣佈爲對象，按鍵被覆蓋的值，而不是設置爲新的值： -

你給了： -

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

它應該是： -

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

然後使用： -

$arrayOfEmails = json_decode($cleanforcharacters,true); 

這會給你正確的結果。
