如何从json中获取结果。使用php

<?php
// JSON字符串
$jsonString = '{"name":"John", "age":30, "city":"New York"}';

// 解码JSON字符串为PHP对象
$data = json_decode($jsonString);

// 获取结果
$name = $data->name;
$age = $data->age;
$city = $data->city;

// 打印结果
echo "Name: " . $name . "<br>";
echo "Age: " . $age . "<br>";
echo "City: " . $city . "<br>";
?>

Name: John
Age: 30
City: New York

<?php
// JSON字符串
$jsonString = '[{"name":"John", "age":30, "city":"New York"}, {"name":"Jane", "age":25, "city":"London"}]';

// 解码JSON字符串为PHP数组
$data = json_decode($jsonString, true);

// 获取结果
$name = $data[0]['name'];
$age = $data[0]['age'];
$city = $data[0]['city'];

// 打印结果
echo "Name: " . $name . "<br>";
echo "Age: " . $age . "<br>";
echo "City: " . $city . "<br>";
?>
