Question

我有一个字符串：

$string='{"person":
                [
                 "name":{"first":"Jhon","last":"Ramos"},
                 "phones":{"cel1":"809-555-4444","cel2":"809-444-           4444","home":"819-515-4434"},
                 "address":{"addr1":"adress numer one","addr2":"adress number two"}
                ]
 }';

我想使用json解析字符串并打印所有子数组的名称，如：名称手机地址

只是名字，而不是价值观。

我该怎么做？

感谢您的帮助。

Answer 1

使用json_decode：

$string = '{"person":
            [
             "name":{"first":"Jhon","last":"Ramos"},
             "phones":{"cel1":"809-555-4444","cel2":"809-444-           4444","home":"819-515-4434"},
             "address":{"addr1":"adress numer one","addr2":"adress number two"}
            ]
}';

$result = json_decode($string, true);

foreach($result['person'] as $key => $val)
{
  print_r($val);
}

你的$ string不是json，所以你必须用$string = str_replace(array("[", "]"), array("{", "}"), $string);

将它转换为json

然后代码为，

 <?php
        $string='{"person":
                        [
                         "name":{"first":"Jhon","last":"Ramos"},
                         "phones":{"cel1":"809-555-4444","cel2":"809-444-           4444","home":"819-515-4434"},
                         "address":{"addr1":"adress numer one","addr2":"adress number two"}
                        ]
         }';

         $string = str_replace(array("[", "]"), array("{", "}"), $string);
         $json = json_decode($string, true);
         foreach($json["person"]  as $key => $value)
            echo $key."\n";
    ?>

输出为，

name
phones
address

从数组中提取文本
