网页编码GB2312(“注意这点，比较重要”),代码如下
当这里关键词为"玻璃移门"时，就无法解析json,但生成的url直接通过浏览器访问就有数据，如果关键词为"手机",就可以正常解析json，file_get_contents得到的数据貌似是utf-8的格式
listItem;}function getLocalIp(){//获得用户ip if(isset($_SERVER['HTTP_CLIENT_IP'])){ $ip=$_SERVER['HTTP_CLIENT_IP']; }elseif(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){ $ip=$_SERVER['HTTP_X_FORWARDED_FOR']; }else{ $ip=$_SERVER['REMOTE_ADDR']; } return $ip;}?> 回复讨论(解决方案)
关键词为"玻璃移门"时，echo $data; 是什么值
关键词为"玻璃移门"时，echo $data; 是什么值
echo 的代码如下，代码太多只能贴出部分，由于是手动截取的listItem节点内的格式可能不正确，或者直接访问（http://110.75.71.20/search_turn_page_iphone.htm?sort=&q=%E7%8E%BB%E7%92%83%E7%A7%BB%E9%97%A8&page=1&showMode=list），注意：我php文件编码是gb2312的,echo 出来的数据在浏览器中必须选utf-8才能正常显示，否则是乱码

$data = str_replace('\\', '\\\\', $data);

你难道不知道json不支持gbk编码么？虽然不会报错也不会出现乱码，但官方已经声明不支持gbk。所以就出现你说的这种情况了。
我来总结一番：
1.json不支持gbk编码；
2.array_walk_recursive($t, 'togbk');//因为你需要的是 gbk 编码的，所以要转一下码
php中json_decode();解析json数据，如果json里有中文数据，是解析不了的。
stripslashes($abc);//去掉可能存在的转义
