android怎么传一个数组给PHP，大神帮我改改下面的代码
我想知道 
ArrayList nameValuePairs = new ArrayList();
nameValuePairs.add(new BasicNameValuePair("id","3"));
nameValuePairs.add(new BasicNameValuePair("name","Guo"));
这两句话怎么用数组传值数据给PHP

------解决方案--------------------

URL传输组很简单，键相同值不同就行了
比如要传 id=[1,2,3]
nameValuePairs.add(new BasicNameValuePair("id","1"));
nameValuePairs.add(new BasicNameValuePair("id","2"));
nameValuePairs.add(new BasicNameValuePair("id","3"));
