Is there a way to detect text browsers using PHP?

I want to serve mobile content for text browsers or browsers without CSS support. Is this possible using PHP?

There aren't that many text based browsers. (I'm using w3m, and then there's only lynx, links, elinks; the others are mostly historic.)

But as a more deterministic alternative (however: cookie dependency!) you could build a trap:

<link rel="stylesheet trap" ref="ping-css.php">

Which simply updates a session or cookie value to check later:

<?php setcookie("css_supported", "yay"); ?> #faux-css { }

A note of concern would be that screenreaders (which are quasi text browsers too) also can consume CSS declarations. And some variants of elinks do too. But then again, you could built a more elaborate trap using @media tty or check via @media screen if it's a graphical browser.

There's the native function get_browser, that returns a bunch of information based on the $_SERVER['HTTP_USER_AGENT'] variable.

You can look at the http User-Agent header via the php global $_SERVER['HTTP_USER_AGENT']. Of course you'll need to know what User-Agents to look for... You could start by searching here: http://www.user-agents.org/
