/**
     *
     * 将简单数组转化为简单的xml
     * @param string $data  要进行转化的数组
     * @param string $tag   要使用的标签
     * @example
     * $arr = array(
        'rtxAccount'=>'aaron','ipAddr'=>'192.168.0.12',
        'conferenceList'=>array('conference'=>
                            array(
                                array('conferenceId'=>1212,'conferenceTitle'=>'quanshi 444','smeAccount'=>''),
                                array('conferenceId'=>454,'conferenceTitle'=>'quanshi meetting','smeAccount'=>''),
                                array('conferenceId'=>6767,'conferenceTitle'=>'quanshi meetting','smeAccount'=>''),
                                array('conferenceId'=>232323,'conferenceTitle'=>'quanshi uuu','smeAccount'=>''),
                                array('conferenceId'=>8989,'conferenceTitle'=>'quanshi meetting','smeAccount'=>''),
                                array('conferenceId'=>1234343212,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'')
                                )
                            )
        );
        转化为：
        aaron
        192.168.0.12
       
           
                1212
                quanshi 444
               
           
           
                454
                quanshi meetting
               
           
           
                6767
                quanshi meetting
               
           
           
                232323
                quanshi uuu
               
           
           
                8989
                quanshi meetting
               
           
           
                1234343212
                quanshi meetting
