Hi, I've just begun today to learn PHP; I'm using the XHTML 1.1 doctype and it works like a charm:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="content-type" content="application/xhtml+xml; charset=utf-8" />
<meta http-equiv="expires" content="-1" />
<meta name="author" content="Ferio"/>
<meta name="Description" content="PHP exercises" />
<meta name="Keywords" content="Exercises, PHP" />
<meta name="Robots" content="all" />
<title>Mi 1st PHP program</title>
</head>
<body>
<?php
echo "Hello World!";
?>
</body>
</html>
The problem is that I wanted to add the XML declaration on top of the code to make it completely XHTML 1.1 compliant:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<meta http-equiv="content-type" content="application/xhtml+xml; charset=utf-8" />
<meta http-equiv="expires" content="-1" />
<meta name="author" content="Ferio"/>
<meta name="Description" content="PHP exercises" />
<meta name="Keywords" content="Exercises, PHP" />
<meta name="Robots" content="all" />
<title>Mi 1st PHP program</title>
</head>
<body>
<?php
echo "Hello World!";
?>
</body>
</html>
But when I do this, Firefox returns:

Parse error: syntax error, unexpected T_STRING in /var/www/firstprog.php on line 1
How could I add this line without getting this error?

because tags begining with <? get confused as php tags by the parser, you have to print or echo the xml line. As <?php echo '<?xml ... '; ?>

I thought it was something like this, but my mind was wondering about escape sequences embedded in the XML code, only God knows why ](*,) Thank you!

no problem! And I am glad a fellow web developer ( or at least a starting one) is taking the proper route to web standards

You don't necessarily need to use PHP to print the XML header. If you turn off PHP short tags, it'll work just as well.
But absolutely true; good you care about that tag. I started off using HTML with IE and it was very error-forgiving. Made me use very very lazy HTML, that I had to fix when I switched to Linux.

I'm not sure why I didn't reply to this when I should, but I just wanted to let you know that, after months studying PHP, I've just got an amazing job, and I wanted to thank you for your participation in this achievement of mine, so: thank you!
