Facebook announced the release of XHP yesterday. It is an extension for PHP which provides enhancements to the PHP language syntax and gives the language some convenient capabilities.

In this post I will provide you links to the essential sources of information about XHP, show some XHP sample code, and discuss the installation process for XHP on Ubuntu with Apache and PHP5.

HowTo: Make IE8 Display Your Website in IE7 Compatibility Mode

To make your website or web page look the same in Internet Explorer 8 as it does in Internet Explorer 7, include the following line in the <head> tag on your page.

<meta content="IE=EmulateIE7" http-equiv="X-UA-Compatible" />

This code tells IE8 to render the page in IE7 compatibility mode. That way you can just worry about making your site work in IE6 and IE7 and not trying to support three concurrent generations of the web browser.

Microsoft has more information about Compatibility View for IE8 on the IEBlog.

You can also tell IE8 to apply compatibility mode by setting the header in your web server. In Apache, you can do this by including the following line in your site config file (or apply it just to a specific directory or page if needed). Make sure you have the Headers module installed.

Header set X-UA-Compatible "IE=EmulateIE7"

More information is available in the Internet Explorer Compatibility Center.
