It's so interesting that some details bug some people and others bug

...I count eight transitions (instances of switching between PHP
syntax and output text) -- one each time you open or close a quote --
compared to just two transitions (the opening & closing labels) for
the comparable heredoc statement:
print <<< hdDay
<option value="$day"$sSelected>$day</option>
hdDay;

That's funny. I count eight transitions in both
examples. The difference in the second example is
that the transition switches have changed from
open/closing quote to '$'/not-a-variable-character.
Yes, from the point of view of the PHP parser, a transition is made each time you encounter an embedded variable requiring evaluation and each time you return to the quoted expression that doesn't require that same kind of evaluation.
What I was referring to were transitions of PHP syntactical punctuation that fragment the expression from the human point of view. I personally find the heredoc expression much easier to read, proofread, and maintain because it appears to be all one simple, unbroken expression.
