PHP禁止直接访问

Question

Is there any possible way to make direct browser access to

http://www.example.com/test.php

Not available when viewing url directly but still allowing

JQuery $.get('http://www.example.com/test.php') function

To read the file? I know this might not be possible because I believe going in my browser and typing http://www.example.com/test.php is basically the same thing on client side as using the $.get() function.. But I didn't know if there was any work arounds for this.

Answer 1

Kinda, have php check for the x-requested-with header. If it is not present, redirect somewhere else.

It doesn't stop someone from sending their own request with said header though.

Answer 2

You are right, using a browser or $.get are basically the same. The only difference is that an AJAX call sets the X-Requested-With header to XMLHttpRequest. This can be added with browser extensions, though, so it is not fool-proof.
