Does the PHP parser analyze microprogramming while reading comments?

Read carefully

The question here is not whether the PHP parser processes comments or not, and the question is not that omitting comments gives more performance to your script or not!

That "Does the PHP parser have a microstate when reading comments?"

Why am I asking?

Due to misconception about the Internet regarding this issue. Some programmers say “YES,” and some answer “NO.” Who should I dodge?

Edit: (Having received mostly comments and an answer requiring time to comment),

Look what i have here

<?php

// Control
echo microtime(), "<br />"; // 0.25163600 1292450508
echo microtime(), "<br />"; // 0.25186000 1292450508

// Test
echo microtime(), "<br />"; // 0.25189700 1292450508
# TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST TEST
# .. Above comment repeated 18809 times ..
echo microtime(), "<br />"; // 0.25192100 1292450508

?>
