Discussion: Array2xml and Xml2array, and _php examples of XML and array conversion

PHP in the background server, often encounter this situation, need to parse the XML file from the front desk, and the data returned in XML format, in this case, XML and PHP associative array conversion is very frequent things. For example, flex and other client programs interact with the server, often using this approach. Here are the two methods I've summed up, which greatly simplifies the effort to transform XML from one array to another.

Copy Code code as follows:

/**
*
* Convert a simple array into a simple XML
* @param string $data the array to be converted
* @param string $tag the label to use
* @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 ')
)
)
);

Xml2array

Copy Code code as follows:

* @param string $xmlString XML string
