<div>
I found a solution by doing the following after I used the GET variables:<br />
<br />

<pre><code id="code-20-41627318-1">if ($_SERVER['QUERY_STRING'] != '') {
  unset($_SERVER['QUERY_STRING']);
  header('Location: '.$_SERVER['HTTP_REFERER']);
  die;
}</code></pre>
I would love to hear comments and specially it it's safe.

Hi guys,<br />
<br />
I'm building a site without Smarty or any other framework so I'm making my own script to validate data, users selections, etc. An example would be when the user changes the language: check against the DB if the GET parameter contains a valid language and cookie him. That and more is being done in a file required before every page but once the visitor clicks on mysite.com/samepage/?lang=<wbr />en I want the page to reload (for which I'm using $_SERVER['REQUEST_URI']), work on the DB and cookie stuff and send him to the same page but with a clean URL (i.e. mysite.com/samepage/).<br />
<br />
What's the best method? regex?<br />
<br />
Thanks in advance!

Clean URL from GET variables

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

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
