New in PHP5: assign default value to
pass-by-reference paramter.
I didn't believe it even when I read
http://devzone.zend.com/article/1714-Whats-New-in-PHP-5
Then I tried this:
<?php
function my_func(&$arg = 22) {
if ($arg == 22) {
print '$arg is '. $arg;
}
}
my_func();
?>
Guess what? It works, even tho' not clear about what $arg is actually referencing!
