No, you don't.
Have a script file that processes your information, then include() a
template
file that would have drop in replacements
file1.php
<?
$name = showusername();
$login = showlastlogin();
include("template.html");
?>
template.html
<html>
Hello <?=$name;?> your last login was <?=$login;?>.
</html>
Your PHP file can get fancy.
file1.php
<?
$template="foo.html";
$name = showusername();
$login = showlastlogin();
if ($login>60 days) {
$template="foolate.html";
}
include($template);
?>
You can check conditionals, handle errors, etc., in your PHP file,
without putting any function calls in your HTML template. We
try to avoid putting function calls in the templates at all costs.
variables - yes. logic (if/else/etc) - yes (on occasion).
function calls? No.

Again - what if showlastlogin returned an error for some reason? How
would you handle that there?
If the 'elegance' is simply saving a few keystrokes, that's not really
doing much. :(

It's not separated enough if you're possibly pulling back stuff from
functions
which you haven't error checked. You would do that error checking in the
template then, which doesn't strike me as very efficient in most cases.
