The point here is that *several* consecutive lines outside of <?php … ?> are 
treated like *one* “echo” statement with the difference that the source code 
is not parsed for language tokens except “<?”.  Beginners are often not 
aware that using several consecutive “echo” statements is comparably 
inefficient.

You have trimmed from your text the false conclusion, which I was referring 
to, that accompanied the correct statement that you left in.
