Essential PHP S&S Elements

Описание: Type Casting: PHP allows casting of values from one type to another. Use the cast syntax (int) , (float) , (string) , (bool) , etc. For example, a numeric string can be cast to an int. Casting is often used to ensure a value’s type or to truncate floats to int. Note that casting a non-numeric string to int yields 0.

$val = "42";
$intVal = (int)$val; // cast string "42" to integer 42
$pi = 3.14;
$intPi = (int)$pi; // cast float 3.14 to int 3 (truncation)
var_dump($intVal, $intPi); // Outputs: int(42), int(3)
