php converts xml For the array number
1. Function:
/*
@desc：xml转数组
@param data xml字符串
@return arr 解析出的数组
*/
function xmltoarray($data){
$obj = simplexml_load_string($data, 'SimpleXMLElement', LIBXML_NOCDATA);
$json = json_encode($obj);
$arr = json_decode($json, true);
return $arr;
}simplexml_load_string() function converts a well-formed XML string into a SimpleXMLElement object.
json_encode() is used to JSON encode variables. This function returns JSON data if executed successfully, otherwise it returns FALSE.
json_decode() function is used to decode a JSON-formatted string and convert it into a PHP variable (object or array).
json_decode ($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.
2. Test:
<?php $string = <<<XML <?xml version='1.0'?> <document> <title>Forty What?</title> <from>Joe</from> <to>Jane</to> <body> I know that's the answer -- but what's the question? </body> </document> XML; $arr = xmltoarray($string); var_dump($arr);b. Output:
array(4) {
["title"]=>
string(11) "Forty What?"
["from"]=>
string(3) "Joe"
["to"]=>
string(4) "Jane"
["body"]=>
string(57) "
