我不能使用環路（PHP）得到JSON數組值

我有1個JSON，但我不能使用用於循環我不能使用環路（PHP）得到JSON數組值

$string = [{"lt":"1","lot":["1","1","1","1","1"]},{"lt":"2","lot":["0","0","0","0","0"]},{"lt":"3","lot":["0","0","0","0","0","0"]}] 
$json = json_decode($string,true); 
for($i = 0;$i<count($json);$i++){ 
    for($j = 0;$j<count($json->lot);$i++){ 
     if($json->lot==0){ 
      echo $j; 
     } 
    } 
}

得到一個值i得到這個錯誤：試圖得到非對象

的屬性

$ JSON是數組，使用'$ JSON [ '很多']'，而不是'$ json-> lot' –

編輯代碼：

$json = [{"lt":"1","lot":["1","1","1","1","1"]},{"lt":"2","lot":["0","0","0","0","0"]},{"lt":"3","lot":["0","0","0","0","0","0"]}] 
$json = json_decode($json); 
for($i = 0;$i<count($json);$i++){ 
    for($j = 0;$j<count($json->lot);$i++){ 
     if($json->lot==0){ 
      echo $j; 
     } 
    }

改變JSON在使用數組PHP json_decode解碼（）。 json_decode

對不起IM忘記添加這對於stackoverflow –

你需要在你的json上使用json_decode。另外，請記住，json必須作爲字符串存儲在PHP中。

<?php 
$json = ['{"lt":"1","lot":["1","1","1","1","1"]}','{"lt":"2","lot":["0","0","0","0","0"]}','{"lt":"3","lot":["0","0","0","0","0","0"]}']; 

foreach($json as $data) { 
    $current = json_decode($data); 

    foreach($current->lot as $lot) 
     echo $lot; 
}

用於json_decode()功能解碼json：

<?php 
$json = '[{"lt":"1","lot":["1","1","1","1","1"]},{"lt":"2","lot":["0","0","0","0","0"]},{"lt":"3","lot":["0","0","0","0","0","0"]}]'; 
$json = json_decode($json); 
foreach($json as $val){ 
    foreach($val->lot as $lot) { 
     if($lot==0){ 
      echo $lot; 
     } 
    } 
} 
?>
