 * @param string $endTime2 结束时间2
 * @return bool
 */function is_time_cross($beginTime1 = '', $endTime1 = '', $beginTime2 = '', $endTime2 = '') {
    $status = $beginTime2 - $beginTime1;    if ($status > 0) {        $status2 = $beginTime2 - $endTime1;        if ($status2 >= 0) {            return false;
