如何使用angularjs和php从数据库中获取最后插入的记录？

app.controller('MyController', function($scope, $http) {
  $http.get('your_php_api_url')
    .then(function(response) {
      $scope.lastRecord = response.data;
    });
});

<?php
// 连接数据库
$servername = "your_servername";
$username = "your_username";
$password = "your_password";
$dbname = "your_dbname";

$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行查询语句
$sql = "SELECT * FROM your_table ORDER BY id DESC LIMIT 1";
$result = $conn->query($sql);

// 获取结果集
if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    echo json_encode($row);
} else {
    echo "0 结果";
}

// 关闭连接
$conn->close();
?>
