Question

Is there any way to retrieve headers from <img> tag using PHP? The <img> has src attribute set to a randomly and dynamic generated PHP image, which sends header that I want to retrieve containing dynamic content based on content of the image.

吉大港山区的头盔由网络服务器确定,他们为图像服务。你们可以通过直接从PHP中获取内容来压倒头脑。然而,这比直接为图像服务的网络服务器要慢得多。大多数网络服务器允许组合确定吉大港山区的主机,以便进行特定档案延期。

<a href="/images/my-image.php?type=png" />

In my-image.php:

<?php
   if( $_REQUEST[ type ] ==  png  ){
        header(  Content-Type: image/png  );
        echo file_get_contents(  /websites/mywebsite.com/web/images/my-image.jpg  );
            exit();
   }
