通过PHP加载图像 [英] Loading an image through PHP

问题描述

我正在尝试通过PHP加载图像，但是我不知道如何. 文件名存储在数据库中，例如image.jpg

I'm trying to load an image through PHP, but I don't know how. The filename is stored in the database, such as image.jpg

if($_GET['image']){
    // Client requesting image, so retrieve it from DB
    $id = mysql_real_escape_string($_GET['image']);
    $sql = "SELECT * FROM $tbl_name WHERE id = '$id' LIMIT 1";
}

客户需要像这样请求图像

The client needs to request an image like so

http://example.com/index.php?image=1

然后它应该返回图像，因此可以像这样嵌入它:

And then it should return the image, so it can be embedded like this:

<img src="http://example.com/index.php?image=1" alt="" />

这可能吗?

推荐答案

$img = 'path/to/image.jpg';
header('Content-Type: image/jpeg');
readfile($img);

刚刚测试
