Example #1 cubrid_drop() example

`<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
@cubrid_execute($conn, "DROP TABLE foo");
cubrid_execute($conn, "CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c list(int), d char(10))");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(2, {4,5,7}, {44,55,66,666}, 'b')");
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
printf("--- Before Drop: ---\n");
$attr = cubrid_get($conn, $oid);
var_dump($attr);
if (cubrid_drop($conn, $oid)) {
cubrid_commit($conn);
} else {
cubrid_rollback($conn);
}
cubrid_close_request($req);
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
printf("\n--- After Drop: ---\n");
$attr = cubrid_get($conn, $oid);
var_dump($attr);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>`

The above example will output:

    --- Before Drop: ---
    array(4) {
      ["a"]=>
      string(1) "1"
      ["b"]=>
      array(3) {
        [0]=>
        string(1) "1"
        [1]=>
        string(1) "2"
        [2]=>
        string(1) "3"
      }
      ["c"]=>
      array(4) {
        [0]=>
        string(2) "11"
        [1]=>
        string(2) "22"
        [2]=>
        string(2) "33"
        [3]=>
        string(3) "333"
      }
      ["d"]=>
      string(10) "a         "
    }

    --- After Drop: ---
    array(4) {
      ["a"]=>
      string(1) "2"
      ["b"]=>
      array(3) {
        [0]=>
        string(1) "4"
        [1]=>
        string(1) "5"
        [2]=>
        string(1) "7"
      }
      ["c"]=>
      array(4) {
        [0]=>
        string(2) "44"
        [1]=>
        string(2) "55"
        [2]=>
        string(2) "66"
        [3]=>
        string(3) "666"
      }
      ["d"]=>
      string(10) "b         "
    }
