【问题描述】：

所以我是 php 的新手，我想问一下这是什么数据类型？它是搅拌还是字符串数组？我怎么能让他们说我是否只想在字符串中使用名称变量。我怎么称呼他们？如果它在 jsonresponse 我该怎么做呢？如果可能的话，我想在显示时使用 mustache 模板。基本上我想单独显示字符串中的每个数据。

这是我收到的数据

string(1247) "[
{
"name": "POSLAJU NEXT DAY",
"service_code": "POSMY-PN-SDP",
"company_code": "POSMY",
"description": "Booking before 11.30am. \\nPickup and delivery in 1-2 days by PosLaju. \\nAvailable on working days days only. \\nNo booking in advance later than tomorrow. \\nYou can also book online and drop your document/parcel at the nearest POSLAJU branch. \\nOnly available on the web. \\nYou have to print the Consignment Note and follow our Packaging Guidelines.",
"instruction": "Please print the Consignment Note and follow our Packaging Guidelines.",
"payment_methods": [],
"cod_rate": 0,
"price": 6
 },
 {
  "name": "SAME DAY - MORNING",
  "service_code": "MDMY-SDD-S-MORNING-KV",
  "company_code": "MDMY",
  "description": "Booking before 8am. \\nPickup before 10am. \\nDelivery 
    before 2pm. \\nBy motorbike. \\nAvailable on working days only. 
   \\nPayment by credit/cash by sender/cash by receiver.",
  "instruction": "Please label your package with our Consignment Note or 
    Tracking No and follow our Packaging Guidelines.",
    "payment_methods": [
    {
      "code": "CASHPICKUP",
      "name": "Cash By Sender",
     "price": "3"
   }
 ],
   "cod_rate": 0.03,
  "price": 15
 }
 ]"

这是jsonresponse中的代码

   {"response":"[\n  {\n    \"name\": \"POSLAJU NEXT DAY\",\n    \"service_code\": \"POSMY-PN-SDP\",\n    \"company_code\": \"POSMY\",\n    \"description\": \"Booking before 11.30am. \\\\nPickup and delivery in 1-2 days by PosLaju. \\\\nAvailable on working days days only. \\\\nNo booking in advance later than tomorrow. \\\\nYou can also book online and drop your document\/parcel at the nearest POSLAJU branch. \\\\nOnly available on the web. \\\\nYou have to print the Consignment Note and follow our Packaging Guidelines.\",\n    \"instruction\": \"Please print the Consignment Note and follow our Packaging Guidelines.\",\n    \"payment_methods\": [],\n    \"cod_rate\": 0,\n    \"price\": 6\n  },\n  {\n    \"name\": \"SAME DAY - MORNING\",\n    \"service_code\": \"MDMY-SDD-S-MORNING-KV\",\n    \"company_code\": \"MDMY\",\n    \"description\": \"Booking before 8am. \\\\nPickup before 10am. \\\\nDelivery before 2pm. \\\\nBy motorbike. \\\\nAvailable on working days only. \\\\nPayment by credit\/cash by sender\/cash by receiver.\",\n    \"instruction\": \"Please label your package with our Consignment Note or Tracking No and follow our Packaging Guidelines.\",\n    \"payment_methods\": [\n      {\n        \"code\": \"CASHPICKUP\",\n        \"name\": \"Cash By Sender\",\n        \"price\": \"3\"\n      }\n    ],\n    \"cod_rate\": 0.03,\n    \"price\": 15\n  }\n]"}

【问题讨论】：

这是 JSON。使用 json_decode()，像这样给定.. stackoverflow.com/questions/56000809/…

标签： php string jsonresponse mustache.php

【解决方案1】：

它称为 JSON（代表 JavaScript Object Notation），这是一种用于在 PHP 和 JavaScript（或任何其他支持语言）之间共享数据的格式。

要在 PHP 中使用 JSON 数据，您必须将获得的字符串传递给 json_decode。这将返回解码的数据，在您的情况下这将是一个数组。然后，您可以像使用普通数组一样访问数据。只需对解码后的字符串做一个 var_dump，你就会看到它包含的数据。

【讨论】：

好的，我知道如何将它发送到 javascript 文件？我需要做一个 jsonresponse 来发送它们吗？
每次 AJAX 调用（从 JS 发送）在 PHP 和 JavaScript 之间交换数据，然后从 PHP 返回 json。

【解决方案2】：

那是 JSON。使用json_decode()https://www.php.net/manual/en/function.json-decode.php或在线json解码器：http://freeonlinetools24.com/json-decode。
