What is bothering me is the following: if variables that are not assigned
a value were to evaluate to false then since false is the same as the
number 1 the following PHP script should print the number 1 but instead
prints nothing:
<?php if (! $a) print $a; ?>
How is this behavior justified?
I could not find anything on this in the PHP manual.
