如何使用php從json對象讀取所有值

Question

這是我的json數據：

Answer 1

使用json_decode 。 它從格式正確的JSON字符串返回PHP對象

假設問題中的字符串存儲在名為$json_str的變量下，則解碼應如下所示

$json_obj = json_decode($json_str);

然后您可以像這樣訪問它

$json_obj->resourceType; // "Patient"

Answer 2

json_decode（） -解碼JSON字符串

例：

<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

?>

輸出：

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

Answer 3

您可以使用PHP JSON庫： http : //php.net/manual/zh/function.json-decode.php

Answer 4

嘗試如下

$obj= json_decode($json,true);
if(!empty($obj->extension))
{
    foreach($obj->extension as $extension)
    {
         echo  $extension->url;
       // similarly others
     }
}
