How do I write this PHP syntax/function?

I have a php function that I have broken down to simplify my question.

Basically, I want the function to insert php code to wherever it's called.

NB.  I don't want it to display code to the viewer, just to the server.

So if I call fake()...it would be as if I had coded:
<span class='sv'><?php echo $message ?></span>


The variable $message is declared earlier on the page..  When fake() is called...it will echo the value of $message inside the span...and the viewer will be able to see what $message says (formatted according to class sv).

I know this question seems silly, but I have simplified my actual code so that I the question can be more easily answered.

Thanks in advance!
Regards
Nick

Is this what you're looking for?
<?php
function fake($message){
	$return = "<span class='sv'>" . $message . "</span>";
	return $return;
}
?>
<?php echo fake("test");  // Outputs: <span class='sv'>test</span> ?>

Set PHP Short Tags on.  This should do it for you.
<?php // RAY_temp_fake.php
function fake($message)
{
   echo "<span class='sv'>$message</span>\n";
}
?>
<!-- CALLING SEQUENCE -->
<br/><?=fake("MY TEXT")?>

You said the $message variable was declared earlier on the page. Then this can be used:
function fake() {
  global $message;
  return '<span class="sv">'.$message.'</span>';
}
 
# Usage:
<?php echo fake(); ?>

thanks for the quick responses...

I was being stupid...  I thought that $message wouldn't be an available variable... can't believe I didn't think of passing it to the function..  I was trying to access the variable remotely..

@Ray:  What do short tags do?

They let you say <?=$var?> in your HTML.  Instead of <?php echo $var; ?>

Just saves typing ;-)
