When php is working as a backend server, it often happens that it needs to parse the xml file from the foreground and return the data in xml format. In this case, the conversion of associative arrays between xml and php is very frequent. flex and other client programs, for example, interact with the server, often using this approach. Here are two methods That I've summarized to greatly simplify the conversion of xml to arrays.
/**
*
* Converts a simple array to a simple array xml
* @param string $data The array to be transformed
* @param string $tag Labels to use
* @example
* $arr = array(
'rtxAccount'=>'aaron','ipAddr'=>'192.168.0.12',
'conferenceList'=>array('conference'=>
array(
array('conferenceId'=>1212,'conferenceTitle'=>'quanshi 444','smeAccount'=>'https://www.ofstack.com'),
array('conferenceId'=>454,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'https://www.ofstack.com'),
array('conferenceId'=>6767,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'https://www.ofstack.com'),
array('conferenceId'=>232323,'conferenceTitle'=>'quanshi uuu','smeAccount'=>'https://www.ofstack.com'),
array('conferenceId'=>8989,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'https://www.ofstack.com'),
array('conferenceId'=>1234343212,'conferenceTitle'=>'quanshi meetting','smeAccount'=>'https://www.ofstack.com')
)
)
);
