php - Why is preg_match_all returning two matches? -

-

I am trying to identify that between double quotes using string in the string using preg_match_all There is a word, but it is either a double quote of repeating results and two sets of first result, either on either side, where the string is being searched, there is only one set.

Here is my code: 

  $ Str = 'test start' test match this "Test End. '; $ Groups = array ();

and generates var dumps:

[2] {<0 array (2) {[0] = & Gt; Array (1) {[0] = & gt; String (17) "" matches this ""} [1] = & gt; Array (1) {[0] = & gt; String (15) "test this match"}}

As you can see the first array is wrong, why preg_match_all is coming back If you are using print_r instead of vardump, then you will be able to see the difference better.

array ([0] => array ([0] = & gt; "Test match From ") [1] => Array (match [0] => test)

The first string is the first and the second is your match.

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...
