Underscore vs Dash
Just a curiosity question, based on my personal preference: why doesn't PHP support dashes for naming conventions? I experimented with using
$full-name="Mike The Frog"; instead of
$full_name="Mike The Frog";, but I found that the preview page couldn't display when I used the dash instead of an underscore.

PHP doesn't allow to use dash (-) and can't start with number digit(1-9) for naming variable
