问题： json字符串，中文Unicode编码，PHP解析问题，谢谢！http://ip.taobao.com/instruct...
接口返回这样的数据，
{"code":0,"data":{"ip":"210.75.225.254","country":"\u4e2d\u56fd","area":"\u534e\u5317",
"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02","county":"","isp":"\u7535\u4fe1",
"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",
"county_id":"-1","isp_id":"100017"}}类似这样的
"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02"php怎么解析出来正确的汉字呢？
谢谢！
json_decode($json,true);
解决方案2:解决办法：
首先自定义一个函数，处理接到接口的数据，将所有Unicode编码的替换为utf8，
function decodeUnicode($str)
{
return preg_replace_callback('/\\\\u([0-9a-f]{4})/i',
create_function(
'$matches',
'return mb_convert_encoding(pack("H*", $matches[1]), "UTF-8", "UCS-2BE");'
),
$str);
}PHP接口获取数据后，先执行这个函数，替换后，再执行 json_decode($str, true),这样直接可以把接口数据转化为数组了
解决方案3:function unicodeDecode($str){
$json = '{"str":"'.$str.'"}';
$arr = json_decode($json,true);
if(empty($arr)) return '';
return $arr['str'];
}
var_dump(json_decode('{"code":0,"data":{"ip":"210.75.225.254","country":"\u4e2d\u56fd","area":"\u534e\u5317",
"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02","county":"","isp":"\u7535\u4fe1",
"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",
"county_id":"-1","isp_id":"100017"}}'));
