Question

I have a conditional statement which goes thusly:

if ($_POST['password'] == $_POST['repeat'] && $_SESSION['type'] == "admin")

But let’s say I also want the conditional to evaluate true to users with type “superuser” (instead of “admin”).

So I could, for example, write:

if ($_POST['password'] == $_POST['repeat'] && $_SESSION['type'] == "admin" || $_SESSION['type'] == "superuser")

But assuming PHP reads conditionals and equations from the left to the right, it’s then possible for a “superuser” to have the conditional evaluate true even if “password” and “repeat” are not equal, since we’re placing imaginary brackets around the two operands next to “&&”, right?

I could add brackets to encapsulate the two operands for “||”, but I recall faintly that I may have tried something in the past, and had it fail spectacularly.

Is there a better way to do this? Do brackets actually work (thus concluding that my memory is faulty? [memory leak? heh.])

Thanks!

Answer 1

Yes, parentheses will override the fact that && has a higher precedence than ||.
