如何使用pdo php mysql在表单字段中显示图像

<form action="upload.php" method="post" enctype="multipart/form-data">
  <input type="file" name="image">
  <input type="submit" value="Upload">
</form>

<?php
// 连接到MySQL数据库
$dsn = "mysql:host=localhost;dbname=your_database;charset=utf8mb4";
$username = "your_username";
$password = "your_password";
$options = [
  PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
  PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
  PDO::ATTR_EMULATE_PREPARES => false,
];
$pdo = new PDO($dsn, $username, $password, $options);

// 获取上传的图像文件
$image = $_FILES['image'];

// 移动图像文件到服务器上的指定位置
$targetPath = "uploads/" . basename($image['name']);
move_uploaded_file($image['tmp_name'], $targetPath);

// 将图像文件的路径保存到数据库
$stmt = $pdo->prepare("INSERT INTO your_table (image_path) VALUES (?)");
$stmt->execute([$targetPath]);

// 显示图像
echo "<img src='$targetPath' alt='Uploaded Image'>";
?>
