使用方法

给定 JSON 结构

<?php

include_once "vendor/autoload.php";

use GELight\conversion\{JsonToSmlConverter};

$json = <<<JSON
{
  "firstName": "John",
  "lastName": "Smith",
  "isAlive": true,
  "age": 27,
  "address": {
    "streetAddress": "21 2nd Street",
    "city": "New York",
    "state": "NY",
    "postalCode": "10021-3100"
	},
  "phoneNumbers": [
    {
      "type": "home",
      "number": "212 555-1234"
    },
    {
      "type": "office",
      "number": "646 555-4567"
    }
  ],
  "children": [
    "Aaron"
  ],
  "spouse": true
}
JSON;

$converter = new JsonToSmlConverter();
$doc = $converter::convert(json_decode($json));
$root = $doc->getRoot();

// Returns the first value of attribute "lastName"
echo $root
    ->attribute("lastName")
    ->getValues()[0];

// Returns the first value of attribute "city" in element "address" 
echo $root
    ->element("address")
    ->attribute("city")
    ->getValues()[0];

// Returns the first value of attribute "number" of second element "phoneNumbers" 
echo $root
    ->element("phoneNumbers")
    ->elements()[1]
    ->attribute("number")
    ->getValues()[0];

// Returns the first value of attribute "children"
echo $root
    ->attribute("children")
    ->getValues()[0];

结果

Smith
New York
646 555-4567
Aaron

生成的 SML 文档结构作为字符串输出

# PHP
$doc->toString();

sml
	firstName John
	lastName Smith
	isAlive 1
	age 27
	address
		streetAddress "21 2nd Street"
		city "New York"
		state NY
		postalCode 10021-3100
	end
	phoneNumbers
		phoneNumber
			type home
			number "212 555-1234"
		end
		phoneNumber
			type office
			number "646 555-4567"
		end
	end
	children Aaron
	spouse 1
end

文档

JsonToSmlConverter

创建一个新的 JSON 到 SML 转换器实例

$converter = new JsonToSmlConverter();

convert

静态方法 "convert" 将您的 JSON 转换为 SML 文档。

convert(object $jsonObject): SmlDocument

$smlDocument = $converter::convert(json_decode($json));
