If you're going to be this picky, you'd better write your own textbook...
:-)
Perhaps instead of a textbook, just use http://php.net/manual
The manual is not nearly enough reference for a beginning students.
You illustrate the problem with quotes in your example above-- why
double quotes with no variable being interpolated?
The . is the documented string operator for concatenation... that's
one of the reasons I dislike the unneeded parentheses with the print
function-- then I have to explain-- before I want to-- arguments to
functions, which is necessary to explain the comma.
