I'm working on a project that involves converting HTML to XHTML. Not strictly sure this is a PHP issue, but testing (so far) has eliminated other possibilities. Can someone offer suggestions why, on the same server (Apache 2.2.8), this works: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"> <html lang="en-US"> <head> <link rel=stylesheet type="text/css" href="proj_default.css" title="ss_default"> <title>Testing html</title> </head> <body> <script language="php"> include 'letters/Disclaimer'; </script> <hr> <address><a href="mailto:roberthuff@xxxxxxx">Robert Huff</a></address> <!-- Created: Wed Jan 19 10:52:50 EST 2005 --> <!-- hhmts start --> Last modified: Mon Jun 2 16:56:19 EDT 2008 <!-- hhmts end --> </body> </html> but this doesn't: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Testing xhtml</title> <link rel="stylesheet" type="text/css" href="proj_default.css" title="ss_default" /> <link rel="icon" type="image/x-icon" href="images/favicon.png" /> <link rel="shortcut icon" type="image/x-icon" href="images/favicon.png" /> </head> <body> <script type="text/php"> include 'letters/Disclaimer'; </script> <hr /> <address><a href="mailto:roberthuff@xxxxxxx">Robert Huff</a></address> <!-- Created: Wed Jan 19 10:52:50 EST 2005 --> <!-- hhmts start --> Last modified: Mon Jun 2 17:37:52 EDT 2008 <!-- hhmts end --> </body> </html> Rspectfully, Robert Huff -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
