Hi!
Phil:
Still I am curious what var_dump($userValues['afterDark']); at line 102.5
would return.
I managed to recreate that fault with
$var['test'] = "blah";
echo ($var['test']);
if( $var['test'] == 0)
{
echo "ok";
}
//this returns blahok -- not expected.
In my case Var_dump() returns string(4) "blah" as expected.
Using
if( $var['test'] === 0)
behaves as expected!!
Are you wanting to only test for a empty/non-empty string?
if so, use this.
if ( empty($var['test']) ) {
echo "var['test'] is empty";
}
Jim:
TypeCasting would only be effective if you used the type sensitive
comparison operator === , because with "==" 0 equals NULL equals false
equals "" and so on ... or do I miss something here??
Hope that solves it for you! I'm still investigating why my first examples
fails. I've got the strong feeling that I'm missing something there. I don't
believe in a php bug or a memory leak in this case! Must be something pretty
obvious! Anyone a clue??
Thanks,
Jan

how can this be? This is not the first time I've run into a
situation like this. What am I missing?
line 102 echo ($userValues['afterDark']); // outputs 1

Add a line at 102.5...
var_dump($userValues['afterDark']);
What type is that variable?
Don't have to do a dump, I know its a tinyint(1), not null, default 0
PHP does not have a type of tinyint
knowing now that this comes from a database, if it is mysql, then it is of
type string
PHP converts all fields when pulled from the database into strings. It does
not take into account
what type the field is actually set to in mysql.
Try puting a (int) in front of the condition like this
if ( (int)$userValues['afterDark'] == 0 ) {
...
}
Maybe this will help
That would be the type in the database, not the type of that variable at
that time.
