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.
