php converts xml For the array number
1. Function:
/*

@param data xml字符串
@return arr 解析出的数组
*/
function xmltoarray($data){

}simplexml_load_string() function converts a well-formed XML string into a SimpleXMLElement object.
json_encode() is used to JSON encode variables. This function returns JSON data if executed successfully, otherwise it returns FALSE.
json_decode() function is used to decode a JSON-formatted string and convert it into a PHP variable (object or array).
json_decode ($json_string [,$assoc = false [, $depth = 512 [, $options = 0 ]]])
Parameters
- ##json_string: JSON string to be decoded, must be UTF-8 encoded data
- assoc: When this parameter is TRUE, an array is returned, and when FALSE, an object is returned.
- depth: Integer type parameter, which specifies the recursion depth
- options: Binary mask, currently only JSON_BIGINT_AS_STRING is supported.
