This PHP code demonstrates the behavior of the intval() function. It converts various input types to an integer.
intval(32)returns the integer 32.intval(3.2)truncates the float and returns 3.intval('32.5')converts the string to 32, ignoring the decimal part.intval([])returns 0 for an empty array.intval(['red','green','blue'])returns 1 for a non-empty array.
This function is useful when you need to ensure a value is a whole number, especially when handling form inputs or calculations.
