What does the 3 = signs mean in a statement like this?


if ("0" === 0) echo "true\n";

which, by the way, equals false.

It means absolutely the same.

1 == '1' will be true because PHP can see that they're the same value

by the same method 0 can be the same as false
any number greater than 0 can be true

but if you use === 0 is a number and false is boolean and they're not the same at all.

does that make sense?

NeedHelp, its the same as == , but where == cant tell the difference between a integer and a string, === is type sensitive.
