Ok i found something very interesting , i have a session var setup to check for a groupID which is an integer,
if ($_SESSION['groupID']==1) { this was working, then when i changed it to
if ($_SESSION['groupID']===1) { per recomendation, it does not now ! i was going through my code and changing things, now i fear it may all break ?
I changed it to if ($_SESSION['groupID']==='1') { and it worked, why was that, is what i did before bad practice ?
I think $_SESSION['groupID'] here is considered a string, which is going to evaluate to 0 (zero) in comparisons. Hence 0 === 1 will return false. However, when you enclose the 1 in quotes, it becomes a string too for comparison, and will evaluate to 0. Someone correct me if I am mistaken.
