php解析json数据

[hongyb701213]

$json = '{"errcode":0,"errmsg":"ok","openid":"ojArVjmlr6uZi2O6Yq******","nickname":"三华","membership_number":"000745805505","sex":"MALE","user_info":{"common_field_list":[{"name":"USER_FORM_INFO_FLAG_SEX","value":"男","value_list":[]},{"name":"USER_FORM_INFO_FLAG_BIRTHDAY","value":"1970-12-13","value_list":[]},{"name":"USER_FORM_INFO_FLAG_NAME","value":"三华","value_list":[]},{"name":"USER_FORM_INFO_FLAG_EMAIL","value":"[e-mail]","value_list":[]}],"custom_field_list":[]},"user_card_status":"NORMAL","has_active":true}';

外层的数据拿到了，但common_field_list 里面的数据不知怎么拿出来，请教各位！

你是怎么获取 的？

$r['user_info']['common_field_list'] 这样不就拿到了吗

$r = json_decode($json, 1);
echo $r['user_info']['common_field_list'][1]['name'];//USER_FORM_INFO_FLAG_BIRTHDAY
