Int

[tqmd1]

What is the difference between following functions?
Does these both functions perform same task?

$wh_ope=clean($_POST['whop'])?(int)$_POST['whop'] : 0;
$wh_ope=(int)clean($_POST['whop']); 


function clean($str)
    {
    $cstr=trim($str);
    $cstr=addslashes($str);
    $cstr=strip_tags($str);
    $cstr=htmlspecialchars($str);
    return $cstr;
    }

Neither are good code. A string is not an integer. The length may be. Any character of the string can be considered an integer, but the string itself is not. What are you trying to accomplish here?

Trying to get zero (0) if there is NULL or empty string.
Want to save 0 instead of NULL.

A string is not an integer.

in PHP, from the POST and GET arrays, you always get strings, even if submitting integers. PHP does automatic type casting, but it can be forced as explained here:
