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
That would be the type in the database, not the type of that variable at that time.

Absolutely right. didn't think of that.
var_dump($userValues['afterDark']); ==> string(1) "1"
but then I'm comparing a string to an int and the result always seems to pass. So does that mean any string compared to any int will be true?
By casting (int)$userValues['afterDark'] the test still passes and var_dump shows the (int)$userValues['afterDark'] as an int(1) but does give a value like the previous example.
ie. string(1)"1" but only int(1) Not sure if the expression has a value of "1" now that its been cast.
Then finally if ( (int)$userValues['afterDark'] === 0 ) { // passes
So:
if ( $userValues['afterDark'] == 0 ) { // passes
if ( (int)$userValues['afterDark'] == 0 ) { // passes
if ( (int)$userValues['afterDark'] === 0 ) { // passes
And the value of afterdark in the mysql table is tinyint(1) 1.
And echo( 1+(int)$userValues['afterDark']); // outputs 2
Now I'm confused!
