Discussion: array2xml, xml2array, and mutual conversion between xml and array _ php instance

This article provides a detailed analysis of the mutual conversion between array2xml, xml2array, and xml and array. if you want to use php as a backend server, you will often encounter this situation, the xml file from the front-end needs to be parsed and the data is returned in xml format. in this case, the conversion of arrays associated with xml and php is very frequent. For example, this method is often used for interaction between flex and other client programs and servers. The following are two methods I have summarized, which greatly simplifies the workload of conversion between xml and arrays.

The code is as follows:

/**
*
* Convert a simple array to a simple xml
* @ Param string $ array of data to be converted
* @ Param string $ tag the tag to use
* @ Example
* $ Arr = array (
'Rtxaccount' => 'Aaron ', 'ipadd' => '2017. 168.0.12 ',
'Conferencelist' => array ('conference '=>
Array (
Array ('ferenceid' => 1212, 'ferencetitle' => 'quanshi 444 ', 'smeaccount' => 'http: // www.jb51.net '),
Array ('ferenceid' => 454, 'ferencetitle' => 'quanshi meetting ', 'smeaccount' => 'http: // www.jb51.net '),
Array ('ferenceid' => 6767, 'ferencetitle' => 'quanshi meetting ', 'smeaccount' => 'http: // www.jb51.net '),
Array ('ferenceid' => 232323, 'ferencetitle' => 'quanshi uuu ', 'smeaccount' => 'http: // www.jb51.net '),
Array ('ferenceid' => 8989, 'ferencetitle' => 'quanshi meetting ', 'smeaccount' => 'http: // www.jb51.net '),
Array ('ferenceid' => 1234343212, 'ferencetitle' => 'quanshi meetting ', 'smeaccount' => 'http: // www.jb51.net ')
)
)
);

The code is as follows:

/**
