使用if语句默认未设置的值

Question

I think there a easier way to perform the same function but without if statements.

if (isset($_GET['limit']))
 {
  $limit = $_GET['limit'];
 }
else
 {
   $limit = 10;
 }

Answer 1

If there is I'd be open to hearing it...

...But I think your best bet is just a short hand if/else statement instead. Not that it really makes any difference.

$limit = (isset($_GET['limit']) ? $_GET['limit'] :  10;
