Interesting, never used strlen for this reason before , does it work
nicely? I am used to using empty() and isset() for such things.
Joe, why do you always have to be so different? ;-) Wonderful how
flexible this all is huh?
At any rate, I would do this :
<?php
if (empty($state))
{
echo 'Enter state please!';
}
else
{
echo 'Your state was '.$state;
}
?>
I know that if $state were '0' then it is not considered empty, but this
does not seem to apply here, right? Always looking for new little tips
...
