怎么把图片存到mysql数据库

CREATE DATABASE image_storage;
USE image_storage;

CREATE TABLE images (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    data LONGBLOB NOT NULL
);

<?php
// 获取上传的图片文件
$image = $_FILES['image']['tmp_name'];

// 将图片转换为二进制数据
$imageData = file_get_contents($image);

// 连接MySQL数据库
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "image_storage";

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

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

// 将图片数据插入到数据库中
$sql = "INSERT INTO images (name, data) VALUES (?, ?)";
$stmt = $conn->prepare($sql);
$stmt->bind_param("ss", $_FILES['image']['name'], $imageData);
$stmt->execute();

// 检查插入结果
if ($stmt->affected_rows > 0) {
    echo "图片上传成功";
} else {
    echo "图片上传失败";
}

// 关闭数据库连接
$stmt->close();
$conn->close();
?>
