php - remove un necessary hierchy from json output -

-

I am creating an administrator backend for the Android app. My code provides a JSN output that the Android developer uses in its app. The developer asked me whether it is possible to reduce hierarchy level in JSL output

json output

Remove highlighted [] 0 and instead of insert content directly inside [] data .

This is my current PHP code 

  if ($ type == 1) // handel item display {try {$ query = "SELECT SELECT FROM CATEGORY"; $ Result = $ DBH-> Query ($ query); While ($ line = $ result- & gt; receive (PDO :: FETCH_ASSOC)) {$ cat = $ row ['category']; $ Query1 = "SELECT *" from the item is catagory = '$ cat' "; $ Value = $ DBH- & gt; Query ($ query1); If ($ line1 = $ value- & gt; get all (PDO :: FETCH_OBJ)) {$ main [] = array ('data' = & gt; array ($ line 1)); } And {$ main [] = array ('data' = & gt; array ('cat' = & gt; $ line ['category'])); }} Echo json_encode ($ main); $ Result-> CloseCursor (); // Close Database Connection Free Resource $ DBH = Faucet; } Hold (PDOException $ e) {print $ e- & gt; GetMessage (); Die (); }}

and Jason production is being generated 

  [["data": [[{"id": "2", "name "Rice", "Price": "20", "Details": "Plain Rice", "Image": "4106_R ice.jpg", "Time": "12 Minutes", "Cat": "Lunch "Item 1", "value": "32", "description": "item 1 description", "image": "1370_2", "sqqqlqilz" {"Id": "4", "name": "hello", "price": "time": "10", "catgary": "lunch", "subcut": "chicken soup" "Lunch": "lunch", "lunch", "lunch": "", "" "" "" "" "" "," image ":" "," time ":" 76 "," catagory ":" lunch "," subcut ":" "}]]]]}, {" date "{" Catagory ": {" catagory ":" test "}} : {" catagory ":" dinner ": {" data ": {" catagory ":" soup "}}, { / Pre> 
 I'm not sure if I made that change or if this could be possible. Is it enabled?

Your Jason Structure is incompatible and try this approach, the developer will be able to parse

["data": [{"id": "2", "name" "" "Time": "12 minutes", "Time": "Rice", "Value": "20", "Details": "Plain" 3 "," name ":" 3 "," name ":" 4106_rice.jpg " "Catagory": "Lunch", "Subcut": ""}, "Item 1", "Keyme ":" 32 "," description ":" Item 1 Description "," Pictures ":" L370_2 Sikeklikljlkllj. "Hello", "price": "" " "", "Description": "fgsdjfsfsdj", "picture": "", "time": "76", "cat": "lunch" {"data": {{"catagory": "soup"} } {{"Catagory": "dinner"}}}, {"data": {{{{{"{{"} ":" test ": {" data ":" subcat ":" "}}}, {" data " "}]}]}

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
