如何在php中获取json数组的值

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

// 将JSON字符串转换为PHP数组
$data = json_decode($jsonString, true);

// 访问JSON数组的值
$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

$jsonString = '{"name":"John", "age":30, "city":"New York", "hobbies":["reading", "painting", "coding"]}';

$data = json_decode($jsonString, true);

$hobbies = $data['hobbies'];
$firstHobby = $hobbies[0];

echo "First Hobby: " . $firstHobby . "<br>";
