Scalar variable naming conventions
Scalar variable naming conventions
- Finally, you might notice that in these
examples, we choose very descriptive names. Rather than saying
for example:
$x = 27;
$y = "Selena Sol";
we say something like the following:
$age = 27;
$full_name = "Selena Sol";
- Though it is not necessary that you make
your scalar variable names descriptive (sometimes it can mean a
lot more typing), I recommend that you do your best to choose
names that will clearly communicate the function of the variable
to you and to others a month or a year down the line.
