Is there a substantial impact in performance (both in the browser and on the server) by exiting and entering the PHP render engine? Example:
<p>Lorem ipsum..</p>
<?php
myPHPfunction();
?>
<p>more html</p>
<?php
anotherPHPfunction();
?>
If this is a big impact in terms of performance, how can I bundle all of the PHP up together, especially if the majority of my pages are static HTML?
