The json_encode function is encoded as null in Chinese.

The json_encode function is encoded as null in Chinese.

 'Age', 'age' => 20); $ jsonencode = json_encode ($ arr); echo $ jsonencode;?>

The program running result is as follows:

 Iconv ('gb2312', 'utf-8', 'Here is the Chinese title'), 'body' => 'abcd... '); Echo json_encode ($ array);?>

The running result of this program is:

{"Title": "\ u8fd9 \ u91cc \ u662f \ u4e2d \ u6587 \ u6807 \ u9898", "body": "abcd ..."}

All Chinese characters in the group are missing after json_encode or \ u2353 is displayed. The solution is to use the urlencode () function to process the following. before json_encode, urlencode () is used to process all the content in the array, and json_encode () is used to convert the content into a json string, finally, use urldecode () to convert the encoded Chinese characters back.

 1000) {die ('possible deep recursion attack');} foreach ($ array as $ key => $ value) {if (is_array ($ value )) {arrayRecursive ($ array [$ key], $ function, $ apply_to_keys_also);} else {$ array [$ key] = $ function ($ value );} if ($ apply_to_keys_also & is_string ($ key) {$ new_key = $ function ($ key); if ($ new_key! = $ Key) {$ array [$ new_key] = $ array [$ key]; unset ($ array [$ key]) ;}}$ recursive_counter -;} /*************************************** * ************************ convert an array to a JSON string (compatible with Chinese characters) * @ param array $ array the array to be converted * @ return string the converted json string * @ access public ***************** **************************************** * ***/function JSON ($ array) {arrayRecursive ($ array, 'urlencode', true); $ json = json_encode ($ array); re Turn urldecode ($ json);} $ array = array ('name' => 'chia', 'age' => 20); echo JSON ($ array);?>

The operation is successful. The result is as follows:

{"Name": "Sia", "Age": "20 ″}
