PHP Browser Detection is a WordPress plugin used to detect a user's browser. It could be used to send conditional CSS files for Internet Explorer, display different content or custom messages anywhere on the page, or to swap out flash for an image for iPhones.

Using the Template Tags in your theme:

Test for specific browsers:

$version is optional. Include a major version number, a single integer - 3,4,5, etc... Or leave it empty to test for any version.

<?php if ( is_firefox($version) ) { do stuff }; ?>

<?php if ( is_safari($version) ) { do stuff }; ?>

<?php if ( is_firefox($version) ) { do stuff }; ?>

<?php if ( is_chrome($version) ) { do stuff }; ?>

<?php if ( is_opera($version) ) { do stuff }; ?>

<?php if ( is_IE($version) ) { do stuff }; ?>

Check for mobile, iPhone, iPad, iPod, etc...

<?php if ( is_iphone($version) ) { do stuff }; ?>

<?php if ( is_ipad($version) ) { do stuff }; ?>

<?php if ( is_ipod($version) ) { do stuff }; ?>

<?php if ( is_mobile() ) { do stuff }; ?>

Check specific versions...

<?php if ( is_IE6() ) { do stuff }; ?>

<?php if ( is_IE7() ) { do stuff }; ?>

<?php if ( is_lt_IE6() ) { do stuff }; ?>

<?php if ( is_lt_IE7() ) { do stuff }; ?>

<?php if ( is_lt_IE8() ) { do stuff }; ?>

Or you can get all the info and do what you want with it:

Get just the name...

<?php $browserName = get_browser_name (); ?>

Get the full version number - 3.2, 5.0, etc...

<?php $browserVersion = get_browser_version (); ?>

Or get it all in array...

<?php $browserInfo = php_browser_info (); ?>
