xml字符串转成数组(php)

 1 $str = '<xml>
 2     <ToUserName> <![CDATA[gh_fc0a06a20993]]> </ToUserName>
 3     <FromUserName> <![CDATA[oZI8Fj040-be6rlDohc6gkoPOQTQ]]> </FromUserName>
 4     <CreateTime>1472549042</CreateTime>
 5     <MsgType> <![CDATA[event]]> </MsgType>
 6     <Event> <![CDATA[user_consume_card]]> </Event>
 7     <CardId> <![CDATA[pZI8Fj8y-E8hpvho2d1ZvpGwQBvA]]> </CardId>
 8     <UserCardCode> <![CDATA[452998530302]]> </UserCardCode>
 9     <ConsumeSource> <![CDATA[FROM_API]]> </ConsumeSource>
10     <LocationName> <![CDATA[]]> </LocationName>
11     <StaffOpenId> <![CDATA[oZ********nJ3bPJu_Rtjkw4c]]> </StaffOpenId>
12     <VerifyCode> <![CDATA[]]> </VerifyCode>
13     <RemarkAmount> <![CDATA[]]> </RemarkAmount>
14     <OuterStr> <![CDATA[xxxxx]]> </OuterStr> 
15 </xml>';
16 
17 $obj = simplexml_load_string($str,"SimpleXMLElement", LIBXML_NOCDATA);
18 $test = json_decode(json_encode($obj),true);
19 $arr = [
20     'FromUserName' => $test['FromUserName'],
21     'ToUserName' => $test['ToUserName'],
22     'CreateTime' => $test['CreateTime'],
23     'CardId' => $test['CardId'],
24     'UserCardCode' => $test['UserCardCode'],
25     'ConsumeSource' => $test['ConsumeSource'],
26     'StaffOpenId' => $test['StaffOpenId']
27 ];
28 $arr = array_map('trim',$arr);
29 var_dump($arr);

在做微信公众号时由于将xml转成对象,每个单独调用时可能会有意外麻烦,所以需要先转成数组,array_map是为了去除空格,因为我发现有部分元素两端是有空格的,造成过功能失效
