php5.4 before the Json_encode when the Chinese will be Unicode encoding, Chinese will be encoded, become unreadable, similar to the "\u***" format, but also to a certain extent, increase the amount of data transferred.
For example:
Copy CodeThe code is as follows:
$str = ' Chinese ';
echo Json_encode ($STR);
"\u4e2d\u6587"
php5.4 start
Echo Json_encode ($str, Json_unescaped_unicode);
Chinese
php5.4 let JSON know more Chinese!
no Unicode transcoding before 5.4, there are 3 ways to handle：
But in fact the first two ways are to cause problems in some special cases. The following example:
Copy CodeThe code is as follows:
function Myjson ($code) {
$code = Json_encode (Urlencodeary ($code));
Return UrlDecode ($code);
}
function Urlencodeary ($data) {
if (Is_array ($data)) {
foreach ($data as $key = = $val) {
$data [$key] = Urlencodeary ($val);
}
return $data;
} else {
Return UrlEncode ($data);
}
}
$test = Array (
0 = ' Dalian Weekly water sub-airport ' → Renmin Road ',
1 = ' Operating Hours: 5:10~21:00 fare: 16 yuan interval of 20 minutes, full at any time of the departure ',
);

Finally summarize a sentence, recommend upgrade to PHP5.4, let PHP more understand Chinese!
