PHP headers

pedroteixeira07

Hello there,

I have a PHP file that sends a header like this:

header('Location: http://www.whatever.com/images/'.$row[1].'.png');

Basiclly what I'm doing is redirecting to the file on the server.

The thing is, I need to send more information other than the picture location.
I need to send another 4 strings that are taken from the database.
Is it possible to send multiple headers? Or is there any other way to go around this?

Since I'm on the subject, how do I send a String on a header?

Thank you very much for your time

What other information? What is this information supposed to do and/or what is supposed to receive and parse this information?

You can send all sorts of headers... though that doesn't mean they'll do anything if the browser doesn't understand them.

You're already doing that... basic form of a header:

Header-Name-Here: String-Value-Here

I need to send that URL, and 4 different Strings.
An android application is receiving this information. For the image link, it transforms the InputStream on a bitmap.
For the other 4 strings I want to transform the InputStream in Strings and use thoose values.

There's a java function that can getAllHeaders. So I'm trusting I can send different headers from PHP and then select them individually in Android for further use.

In that case sure, you can send the related information along in any number of custom headers (which are normally prepended with 'X-'), e.g.:

header("X-Application-ID: $appID");
header("X-Custom-Foobar: $baz");
// etc.

I'll try that then. Thank you very much 😉
