When using
<php
while ($var = current($array) {
#do stuff
next($aray)
?>
to process an array, if current($array) happens to be falsy but not === false it will still end the
loop. In such a case strict typing must be used.
Like this:
<php
while (($var = current($array)) !== FALSE) {
#do stuff
next($aray)
?>
Of course if your array may contain actual FALSE values you will have to deal with those some other
way.
