When PHP is working as a back-end server, it often encounters this situation. It needs to parse the xml file from the front-end and return the data in xml format. In this case, the conversion between xml and the associative array in PHP is Very frequent thing. For example, flex and other client programs often use this method to interact with the server. The following are two methods I have summarized, which greatly simplify the workload of converting xml and array.

Copy code The code is as follows:

/**
     *
     * 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'=>'http://www.jb51.net'),
                                array('conferenceId'=>454,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net'),
                                array('conferenceId'=>6767,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net'),
                                array('conferenceId'=>232323,'conferenceTitle'=>'quanshi uuu','smeAccount'=>'http://www.jb51.net'),
                                array('conferenceId'=>8989,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net'),
                                array('conferenceId'=>1234343212,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'http://www.jb51.net')
                                )
                            )
        );
