如何解码php json数组？

Question

我想显示名称和类型，但不起作用。我该怎么办？

$ json：

{"222":{"id":"222","name":"Shirt1","type":"Men","product":"1","count":"2","price":7000},"223":{"id":"223","name":"Shirt2","type":"Men","product":"2","count":"1","price":4000},"224":{"id":"224","name":"Shirt3","product":"3","count":"2","price":14000}}

解码：

$products = json_decode($json, true);
foreach ($products['id'] as $k => $v)
{
    var_dump(array_key_exists('name', $v));
}

Answer 1

$products = json_decode($json, true);

$result = '';

foreach( $products as $product ) {
   $result .= 'Name : ' . $product['name'] . ', type : ' . $product['type'] . ';';
}

echo $result;
