I am sure there will be some that think that my practice is an
overkill, or not "good practice", but it's a good thing that we all
have a choice. Make your choice to best serve how you want your code
to look.
As per http://us3.php.net/echo
echo() is not actually a function (it is a language construct), so you are
not required to use parentheses with it. echo() (unlike some other language
constructs) does not behave like a function, so it cannot always be used in
the context of a function. Additionally, if you want to pass more than one
parameter to echo(), the parameters must not be enclosed within
parentheses.
So you might want to reconsider your coding practice/style here and use the
construct as designed or you might end up with a far worse scenario than
short-tags could ever provide. Something more along the Python "print"
debacle.
Also, for the love of God, please don't embed a variable into a literal
string and use preprocessing.
Do it like so:
<?php echo 'The answer is '.$answer; ?>
Daevid:
I'm aware that echo is a language construct and does not require the
(). However, please note the reference you provided, namely:
http://us3.php.net/echo
They use "echo()" to describe the construct -- so, if they can use
it, then I figure I'm in good company.
I also practice using () because it is easier for *me* to read,
understand, and document my work. You are free to do as you want.
As for the Python "print" problem, I don't do Python -- so, it can
win the lottery, or die, I don't care.
As for "don't embed a variable into a literal string and use
preprocessing", as I said above, I often do this:
<?php echo("The answer is $answer");?>
and find no problems whatsoever in doing so.
However, I wouldn't do this:
<?php echo 'The answer is '.$answer; ?>
OR, I would place a space before/after the . (i.e., 'The answer is '
. $answer). However, I don't like doing that because I also program
in other languages, which use the dot operator differently.
My experience has shown me that most, if not all, languages are
merging -- as such, I think the dot operator is more established as
something other than just an operation to combine strings.
Cheers,
tedd
