Question

if I had several websites and I would want to read “file.html” in every website, how should I do that? The file.html would be just like this:

<h1>Hot news</h1>
<p>article</p>

I know I can use php include or require,

<? include 'file.html'; ?>

or jQuery, but only within a domain.

.load("file.html");

How should I do that cross-domain?

PS: And yes, I know that’s insecure

Answer 1

You can use PHP for it:

<?php echo file_get_contents('http://....'); ?>

The reason why include doesn’t work is that url includes are disabled by default since they are horribly insecure – the included document is handled as PHP. However, with file_get_contents no PHP code can be injected and thus it’s pretty safe (except client-side things such as XSS if the remote site sends you bad JavaScript code).
