Hi,
Say you have a querystring - index.php?myname=joe
To determine whether myname has a value I have come to the following
conclusions / shortcomings when using one of the following:
ISSET = as long as the variable myname exists it's set, but there's no
guarantee of a value
!EMPTY = if your name = 0 (zero) then it's considered empty, for all
else it seems to work
STRLEN = I have found this to be the only sure way to know.
Is there any other way, or should we always use a combination of ISSET
and STRLEN?
Wouldn't this work?
if(isset($_GET['var']) && !empty($_GET['var'])){
// do something...
}
