Re: [PHP] UNLESS Statement Equivalent

Angela,

the variable $current_page does not exist. so $curent_page does not equal
$saved_page.  Also the ! in front of the entire statement means that all of
this is false.  Since one items is true and not true = false "Don't save"
is echoed out.

If you are looking to save the results based on the above sample it would
look like


if(($page === $saved_page) && ($current_ip === $saved_ip) && ($current_dt <
($saved_dt +3600)) {
 //save the results
} else {
//don't save
}

I would also suggest keeping with your original statement to return early
and return often. Its best to exit out of your functions sooner than later.
 Specially if its a large function.
