PHP in the background server, often encounter this situation, need to parse the XML file from the foreground, and return the data 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 my two methods, which greatly simplifies the conversion of XML to arrays.
Copy CodeThe code is as follows:
/**
*
* Convert simple arrays to simple XML
* @param string $data the array to be converted
* @param string $tag the label to use
* @example
* $arr = Array (
' Rtxaccount ' = ' Aaron ', ' ipaddr ' and ' 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 ')
)
)
);
