在 PHP 中它看起来像这样:
<?php
$cs = new QES_ContentServer(); //Not a real php class, but doesn't look like a native ASP.NET class either, still, it's a class instantiation, little Google shows it's a class for Qwam E-Content Server.
$state = ""; //Superfluous in PHP, don't need to define variables before use except in certain logic related circumstances, of course, the ASP.NET could have been done in one line like "string state = Request.Url.AbsoluteUri.ToString();"
$state = $_SERVER['REQUEST_URI']; //REQUEST_URI actually isn't the best, but it's pretty close. Request.Url.AbsoluteUri is the absolute uri used to call the page. REQUEST_URI would return something like /index.php while Request.Url.AbsoluteUri would give http://www.domain.com/index.php
//$state = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; or something similar might be better in this case given the above
echo $cs->GetXhtml($state); //GetXhtml would be a method of QES.ContentServer, Response.Write is like echo or print.
?>
