使用php从mysql数据库中读取图像文件

Question

I am trying to display an image, but my webpage displays encoding stuff instead. Below is my code:

<?php ob_start();?>

// html markups goes here

<?php include 'login.php';
if(isset($_GET['productid'])){
    $productid = $_GET['productid'];

    $sql = "select tyre_image from tyres where product_id = '$productid'";
    $result = mysql_query($sql) or die(mysql_error());
    header("Content-type :image/jpg");
    echo mysql_result($result,0);

}

ob_end_flush();

?>

I am using $_GET associative array($_GET['variable']) to get the product ID via a link on another page.

How would I fix this?

Answer 1

I had no idea the Content-type header was this picky, but change the spacing around the colon (and also image/jpg should be image/jpeg ):

header("Content-type: image/jpeg");

Per the answer below, I agree - this fix assumes that this script is just used for displaying an image in your HTML, ala <img src="path/to/your/image.php?productid=123" /> .
