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";
