Subject: Re: [PHP-DEV] is_int/is_numeric possible bug
From: unknown@simplemachines.org ("Unknown W. Brackets")

If you're having that problem that a request variable is being reported 
as an integer, I suggest using var_dump().  That function will tell you 
the type and contents of a variable.  For example:

$bool = true;
$int = 1;
$float = 1.0;
$str = 'abc';
$array = array();

var_dump($bool, $int, $float, $str, $array);

Will give you:

bool(true)
int(1)
float(1)
string(3) "abc"
array(0) {
}

All of the above are very different.  A request variable should always 
be of type string, and if one is not then I suspect that may indeed be a 
bug.

Remember that PHP doesn't hide the type from you, it just simplifies 
conversions and usage for you.

In any case, if you want it to be 10 if it wasn't set to a valid int, I 
think you want:

$_REQUEST['days'] = is_numeric($_REQUEST['days']) ? (int) 
$_REQUEST['days'] : 10;

Or similar.  Note that this will treat "5.1" as 5, not as 10 (which may 
be what you want.)
