is() public static method

If $data is not an string, then returned value will always be false. Serialized data is always a string.

public static is ( mixed $data ) : boolean
$data	mixed	Value to check to see if was serialized
return	boolean

    public static function is($data)
    {
        // If it isn't a string, it isn't serialized
        if (!is_string($data)) {
            return false;
        }
        $data = trim($data);
        // Is it the serialized NULL value?
        if ($data === 'N;') {
            return true;
        } elseif ($data === 'b:0;' || $data === 'b:1;') {
            // Is it a serialized boolean?
            return true;
        }
        $length = strlen($data);
        // Check some basic requirements of all serialized strings
        if (self::_checkBasic($data, $length)) {
            return false;
        }
        return @unserialize($data) !== false;
    }
