你必须这样给予:

echo  $json_a['John']['status']; 

echo "<>"

echo  $json_a['Jennifer']['status'];

br inside <>

结果是:

wait
active

$json_a = json_decode($string, TRUE);
$json_o = json_decode($string);



foreach($json_a as $person => $value)
{
    foreach($value as $key => $personal)
    {
        echo $person. " with ".$key . " is ".$personal;
        echo "<br>";
    }

}

要遍历多维数组，可以使用RecursiveArrayIterator

$jsonIterator = new RecursiveIteratorIterator(
    new RecursiveArrayIterator(json_decode($json, TRUE)),
    RecursiveIteratorIterator::SELF_FIRST);

foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:\n";
    } else {
        echo "$key => $val\n";
    }
}

输出:

John:
status => Wait
Jennifer:
status => Active
James:
status => Active
age => 56
count => 10
progress => 0.0029857
bad => 0

在代码板上运行

我完全无法理解，居然没有人指出你开头的“标签”是错的。你可以用{}创建一个对象，而你可以用[]创建一个数组。

[ // <-- Note that I changed this
    {
        "name" : "john", // And moved the name here.
        "status":"Wait"
    },
    {
        "name" : "Jennifer",
        "status":"Active"
    },
    {
        "name" : "James",
        "status":"Active",
        "age":56,
        "count":10,
        "progress":0.0029857,
        "bad":0
    }
] // <-- And this.

有了这个更改，json将被解析为数组而不是对象。有了这个数组，你可以做任何你想做的事情，比如循环等等。

最优雅的解决方案:

$shipments = json_decode(file_get_contents("shipments.js"), true);
print_r($shipments);

请记住，json文件必须使用UTF-8编码，不包含BOM。如果文件有BOM，那么json_decode将返回NULL。

另外:

$shipments = json_encode(json_decode(file_get_contents("shipments.js"), true));
echo $shipments;

试试这个

    $json_data = '{
    "John": {
        "status":"Wait"
    },
    "Jennifer": {
        "status":"Active"
    },
    "James": {
        "status":"Active",
        "age":56,
        "count":10,
        "progress":0.0029857,
        "bad":0
      }
     }';

    $decode_data = json_decode($json_data);
    foreach($decode_data as $key=>$value){

            print_r($value);
    }
