<div>
Without knowing more about the rest of your app, it's difficult to know. For example, what happens in panel/index.php or admin/index.php - it's possible that this page tries to redirect to there, that page doesn't think there's a user logged in so redirects back to the login page - and so on!!<br />
<br />
Also, you're logic seems a little off.<br />
<br />
If 'type' is anything but Admin, the first if block will be fired.<br />
If it is Admin, then the second block will be fired<br />
The third block will never be fired!

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

Web Languages and Standards

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.
