如何利用PHP和Vue實現倉庫管理的會員管理功能

$conn = new mysqli("localhost", "username", "password", "database");

if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

$sql = "SELECT * FROM members";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    $members = array();
    while ($row = $result->fetch_assoc()) {
        $members[] = $row;
    }
    echo json_encode($members);
} else {
    echo "暂无会员信息";
}

$name = $_POST["name"];
$phone = $_POST["phone"];
$idCard = $_POST["idCard"];

$sql = "INSERT INTO members (name, phone, id_card) VALUES ('$name', '$phone', '$idCard')";

if ($conn->query($sql) === TRUE) {
    echo "添加会员成功";
} else {
    echo "添加会员失败: " . $conn->error;
}

$id = $_POST["id"];

$sql = "DELETE FROM members WHERE id=$id";

if ($conn->query($sql) === TRUE) {
    echo "删除会员成功";
} else {
    echo "删除会员失败: " . $conn->error;
}

new Vue({
  el: '#app',
  data: {
    members: []
  },
  mounted() {
    this.fetchMembers();
  },
  methods: {
    fetchMembers() {
      axios.get('member.php')
        .then(response => {
          this.members = response.data;
        })
        .catch(error => {
          console.log(error);
        });
    }
  }
});
