Note Submitter: mwild at iee dot NO_SP_AM dot org ---- The text between <script> and </script> in XHTML is PCDATA, so < and & characters in it should be interpreted as markup. This is a bit limiting for PHP, which is often used to output tags, though you can of course use &lt; and &amp; instead. To avoid that, which makes your code look peculiar and is easy to forget to do, you can mark the PHP as CDATA, eg : <script language="PHP"> //<![CDATA[ echo('Today is <b>'.date('l F jS').'</b>'); //]]> </script> If you don't do this, and your code contains < or &, it should be rejected by an XHTML validator.
