True, but you also have to be careful about that. As mentioned in the PHP
docs, this can lead to weird operator precedence results. For example,
if ( include( "$IP/resources/Resources.php" ) === false ) {
will not work as expected. It looks like a quick check to see if the
included file was successfully included, but PHP will first evaluate the
=== operator before the include statement.
