使用PHP在JSON数组中进一步检索数据

<?php
// JSON字符串
$json = '{
    "employees": [
        {
            "firstName": "John",
            "lastName": "Doe"
        },
        {
            "firstName": "Jane",
            "lastName": "Smith"
        }
    ]
}';

// 将JSON字符串解码为PHP数组
$data = json_decode($json, true);

// 检索数据
$firstName = $data['employees'][0]['firstName'];
$lastName = $data['employees'][0]['lastName'];

// 输出结果
echo "First Name: " . $firstName . "<br>";
echo "Last Name: " . $lastName;
?>

First Name: John
Last Name: Doe
