我是PHP的新手,我在显示数据库中的图像时遇到问题。关于这一点有很多文章和帖子,但没有什么对我有用。

图像在数据库中正确保存,我可以看到

这是我的代码:

saveimage.php

function uploadImage($name, $image, $type) {
    require 'db_config.php';
    /* @var $DBH PDO */
    try {
        $STH = $DBH->prepare("INSERT INTO images (name,image,type) VALUES (:name ,:image,:type)");
        $STH->bindParam(':name', $name);
        $STH->bindParam(':image', $image);
        $STH->bindParam(':type', $type);
        $STH->execute();

        $DBH = null;
    } catch (Exception $ex) {
        echo "Error: " . $ex->getMessage();
    }
}

showimage.php

require 'db_config.php';
/* @var $DBH PDO */

if (isset($_GET['id'])) {
    try {
        $id = $_GET['id'];
        $STH = $DBH->prepare("SELECT name,image,type FROM images WHERE id=" . $id);
        $STH->execute();

        $image = $STH->fetch(PDO::FETCH_OBJ);

        $DBH = null;

        header("Content-Type: " . $image->type);
        header("Content-Length: " . filesize($image->name));
        echo $image->image;
    } catch (Exception $ex) {
        echo "Error: " . $ex->getMessage();
    }
}

的index.php:

<div>
        <img src="showimage.php?id=5" width="200" height="200">
</div>
