Why are you assigning it to a variable? It's quicker just to output it directly onto the screen.

<head>
<title>Register</title>
</head>
<body>
<form action="" method="post">
Name: <input type="text" name="name"

<?
echo ($name_good) ? ' class="field_good" title="enter your name" ' : ' class="field_bad" title="name is in use" ';
?>

>
<input type="submit" name="reg" value="Join Now!">
</form>
</body>
</html>

Also use ' to encapsulate strings as they are quicker than ", as " marks compile the string to check for variables, hence why they are slower.

I suggest you look into using a template engine, such as Smarty[^], to format your pages.

If at first you don't succeed, you're not Chuck Norris.

Template engines just add another layer that IMHO is not needed and does little more than complicate a design and add to the learning.

My file structure is also way more simplistic than a template engine. I do not have to hunt a templates code to find where they buried a code fragment.

With echo once something is echoed its gone to the browser.

Currently I am updating my js knowledge to the current standards of code separation...(i.e.: removing things like ...to and js adding the event logic at the end page load.).

$(document).ready(function() {

I am also contemplating an issue of external (multiple) css file loads vs style tags with css loaded based on page need using php code logic. I suspect in projects with a large number css rules can be refined to reduce the file size (sent to the browser) by send only the needed rules without the need for a larger number of file reads (split css files). But this flies in the face of separation of style from html...and I need to test, well I first need to figure out how I could test.
