setting boolean php code example
Example 1: php is boolean
The is_bool() function checks whether a variable is a boolean or not. This function returns true (1) if the variable is a boolean, otherwise it returns false/nothing.
Example 2: php boolean
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";
