Based on...?
I just thought that it's a higher level thing, so first it must be
replaced with echo, and then interpreted, which would add some minor
decrease in performance (just for the sake of philosophy, of course
it's virtually nothing). Am I wrong? Is it interpreted right away as
an echo without preprocessing?
If you don't want to guess you can always use VLD:
$ php -d enable_short_tags=true -d vld.active=1
<?php echo 'x'; ?>
<? echo 'x'; ?>
<?='x'?>
