PDO Working With BLOBs (get image from table)

本文关键字：获取图像使用 blob PDO | 更新日期: 2023-09-27

我有一个小问题，从数据库表中获取图像，也许有人可以帮助我。我有一个名为:

的数据库

 -RESPONSES with next rows->
id,
user_avatar,
first_name,
last_name,
msg_user,
user_date,

AND

if (isset($_POST['r_sub'])) {
    $image = $_FILES['r_image'];
    $user_name = $_POST['r_username'];
    $last_u_name = $_POST['r_lastname'];
    $user_msg = $_POST['r_usermsg'];
    $u_date = $_POST['r_date'];
    $q_r = "INSERT INTO responses (user_avatar, first_name, last_name, msg_user, user_date) VALUES (:image, :user_name, :last_u_name, :user_msg, :u_date);";
    $query_r = $pdo->prepare($q_r);
    $results = $query_r->execute(array(
        ":image" => $image,
        ":user_name" => $user_name,
        ":last_u_name" => $last_u_name,
        ":user_msg" => $user_msg,
        ":u_date" => $u_date));
    header("Location: index.php");

我想知道如何从表中获得BLOB(在我的情况下:user_avatar);也许有人有现成的解决方案?我真的需要一个代码示例!

try this

echo '<img src="data:image/jpeg;base64,'.base64_encode($image->load()) .'" />';

确保

$image->load()

是从数据库中选择的图像
