Well, the actual code is hard to tell. It's grabbed from a db so it
should be an int. But it's also run through some functions. That's why
I'd like a to tell what's going on better.
The variable is always set. Basically
$result = mssql_query($sql);
$row = mssql_fetch_array($result);
$var = $row[0];
So it should be an int. And if it's copied into a function it
shouldn't be changed.
But doing
if($var)
doesn't seem to work after I upgraded versions. Which is making me
think that they changed how that works.
And using is_string() or is_int() is pointless 'cause it doesn't
matter. I just want to know if the value != 0.
The problem is, if 0 gets changed to "0" somewhere throughout. That's
why I've always used if($var) because it's usually not cared what the
type is, but it seems to now.
