Do proliferation of PHP tags affect speed?

Are scripts that have lots of <?PHP..?> tags taking hits on execution speed, or does this actually enhance speed? Or, on the other hand, does it have no effect?

Example from book:

PHP Code:


		
			
<?php

  // ... some PHP here...

?>



<html>

<head>

<?php

// admin page

require_once('db_login') ;

?>



<title>



<?php

// print the window title and the topmost body heading

$doc_title = "Category Administration" ;

echo "$doc_title\n" ;

?>



</title>

</head>

<body>

<h1>



<?php

echo "$doc_title\n" ;

?>



</h1>

If there is an effect it would be negligible at best. PHP put in HTML is easier to read and modify than HTML echo'd from PHP.

If it does slow anything down the difference would be negligible at best and it's not often these micro optimizations that make a different but rather how to the application is designed that really slows things down when the site grows.

( On a side note, echo is actually notoriously slow on large chunks of data to my understanding )

I think #2 applies. However, I don't fully understand because of the way it was worded.
