json 代表 javascript 对象表示法。它是一种轻量级数据格式,用于在系统之间存储和交换信息,尤其是在 web 应用程序中。
将 json 视为一种以清晰、结构化的格式编写和组织数据的方法。
{
"name": "alice",
"age": 25,
"isstudent": false,
"skills": ["javascript", "python", "html"],
"address": {
"street": "123 main st",
"city": "wonderland"
}
}
{
"users": [
{
"id": 1,
"name": "john",
"email": "john@example.com"
},
{
"id": 2,
"name": "jane",
"email": "jane@example.com"
}
]
}
javascript 示例:
// json data as a string
const jsondata = '{"name": "alice", "age": 25}';
// parse json into an object
const user = json.parse(jsondata);
console.log(user.name); // output: alice
// convert object to json
const newjson = json.stringify(user);
console.log(newjson); // output: {"name":"alice","age":25}

<?php
$data = [
"name" => "alice",
"age" => 25,
"isstudent" => false,
"skills" => ["php", "javascript", "html"],
"address" => [
"street" => "123 main st",
"city" => "wonderland"
]
];
// convert php array to json
$jsondata = json_encode($data, json_pretty_print);
echo $jsondata;
?>
示例:json 到 php 对象:
<?php
$jsondata = '{
"name": "alice",
"age": 25,
"isstudent": false,
"skills": ["php", "javascript", "html"],
"address": {
"street": "123 main st",
"city": "wonderland"
}
}';
// convert json to php object
$phpobject = json_decode($jsondata);
echo $phpobject->name; // output: alice
echo $phpobject->address->city; // output: wonderland
?>
示例:json 到 php 数组:
<?php // Decode JSON to PHP array $phpArray = json_decode($jsonData, true); echo $phpArray['name']; // Output: Alice echo $phpArray['address']['city']; // Output: Wonderland ?>
