如何在同一页面上使用多个PHP标头内容类型？ 这可能吗？

Question

Is it possible to use multiple header types in one document? For example:

header("Content-type: image/jpeg");
header('Content-Type: text/html; charset=utf-8');

returns the whole page as text/html... while

header('Content-Type: text/html; charset=utf-8');
header("Content-type: image/jpeg");

Returns the whole page as an image.... How can I use both types of content on the same page? I'm using ob_start() at the top and ob_end_flush() at the beginning.

Answer 1

You can't. But what you can do is something like this in your HTML:

<img src="my_img.php" />

Of course my_img.php would be a PHP file that has a header("Content-type: image/jpeg"); line, and outputs your image.
