PHP returns JSON

Recently made WebApp want to use PHP to do the backstage, in JSON way to return data.

Use in the background directly at the beginning

<? PHP // ... Echo ' {' result ': true, ' info ': ' '} '?>

Form returned, the foreground Ajax developed the return data type as "JSON".

Found that this does not work, checked the information. PHP return JSON to have Json_encode ()

and changed it to the following.

<? PHP // ... echo json_encode (' {' result ': true, ' info ': ' ... '} ')?>

This way back to JSON is really no problem, but the Chinese characters in the time will be garbled, continue to modify

<? PHP // ... $arr= ' {' result ': true, ' info ': ' Chinese will be garbled '} '; foreach ($arras$key= +$value  ) {$arr[$key]=  UrlEncode($value);} Echo UrlDecode (Json_encode ($arr));? >

So the return of Chinese will not garbled (to be continued)
