这种数据类型是什么，我如何调用数据来单独显示它

Question

所以我是 php 的新手，我想问一下这是什么类型的数据？它是一个搅拌还是一个字符串数组？如果我只想在字符串中使用 name 变量，我该如何让他们说。我怎么能打电话给他们？如果它在 jsonresponse 中，我该怎么做？如果可能，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

它称为 JSON（代表 JavaScript Object Notation），它是一种用于在 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. 这将返回解码后的数据，在您的情况下将是一个数组。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执行 var_dump，您就会看到它包含的数据。
