	      cubrid_drop(3) 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: ---
");
	      $attr = cubrid_get($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("
--- After Drop: ---
");
	      $attr = cubrid_get($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"
