Return in a function - PHP -

-

Even if I understand what everything is doing, then I argue that < Code> Returns $ toggle below the working code:

I do my work and call it back by repeating it, but what happens in that return $ totaal function? I never called it, but without that return I get an empty place.

I should have lost some kind of logic in my mind ....

return gives the word itself (returns back) something.
In this case either $ var1 + $ var2 or $ var1 - $ var2 .

The variables inside a function can not be reached generally outside of it.
with return but you can get something from within the function to get it

Keep in mind that the execution of a return function will end.

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...
