Booleans can be one of two constants:
true
false
These values are not case sensitive, therefore true is the same as TRUE
booleans are also often used in control structures, either directly or as
a result of an operation. For example:
if ($waterDrankToday > 3.7) {
echo "Good work staying hydrated!";
if ($havingABadDay)
hug();
}
else
echo "You should drink more water";Copyright © 2021 Codeinu
