The x & 1 checks if the last bit is set in the number (because 1 Is a number with all bits set to 1 except for the least significant bit): If it is, the number is odd, otherwise even. Logical AND (&&) evaluates operands from left to right, returning immediately with the value of the first falsy operand it encounters; if all values are truthy, the value of the last operand is returned.If a value can be converted to true, the value is so-called truthy.If a value can be converted to false, the value is so-called falsy.. = $a = 'False'; settype($a,'boolean'); var_dump($a); will indeed return false. If the attribute is specified, its value must not be the empty string or isindex..
