However, i'm not sure on the last piece of code...the part i am struggling with is the foreach part: foreach ($_SESSION['openChatBoxes'] as $chatbox => $time) { } If you are interested the full script is here which i am trying to convert: <?php /* Copyright (c) 2009 Anant Garg (anantgarg.com | inscripts.com) This script may be used for non-commercial purposes only.

Hi all... I am an experienced Asp.Net developer, but I need to convert a PHP script to ASP.net. I'm not looking for someone to do the whole conversion, i just need some help understanding what it's actually doing. $items .= <<<EOD { "s": "0", "f": "{$chat['from']}", "m": "{$chat['message']}" }, EOD; $_SESSION['chatHistory'][$chat['from']] .= <<<EOD { "s": "0", "f": "{$chat['from']}", "m": "{$chat['message']}" }, EOD; foreach ($_SESSION['openChatBoxes'] as $chatbox => $time) { if (!isset($_SESSION['tsChatBoxes'][$chatbox])) { $now = time()-strtotime($time); $time = date('g:iA M dS', strtotime($time)); $message = "Sent at $time"; if ($now > 180) { $items .= <<<EOD { "s": "2", "f": "$chatbox", "m": "{$message}" }, EOD; if (!isset($_SESSION['chatHistory'][$chatbox])) { $_SESSION['chatHistory'][$chatbox] = ''; } $_SESSION['chatHistory'][$chatbox] .= <<<EOD { "s": "2", "f": "$chatbox", "m": "{$message}" }, EOD; $_SESSION['tsChatBoxes'][$chatbox] = 1; } } } } Thank you very much in advanced i really appreciate your help!
