cubrid_col_get — Get contents of collection type column using OID

### Description

array cubrid_col_get ( resource `$conn_identifier` , string `$oid` , string `$attr_name` )

The cubrid_col_get() function is used to get contents of the elements of the collection type (set, multiset, sequence) attribute you requested as an array.

### Parameters

`conn_identifier`

  Connection identifier.

`oid`

  OID of the instance that you want to read.

`attr_name`

  Attribute name that you want to read from the instance.

### Return Values

Array (0-based numerical array) containing the elements you requested, when process is successful;

`FALSE` (to distinguish the error from the situation of attribute having empty collection or NULL, in case of error, a warning message is shown; in such case you can check the error by using cubrid_error_code()), when process is unsuccessful.

### Examples

Example #1 cubrid_col_get() example

`<?php
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");
@cubrid_execute($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')");
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
$attr = cubrid_col_get($conn, $oid, "b");
var_dump($attr);
$size = cubrid_col_size($conn, $oid, "b");
var_dump($size);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>`

The above example will output:

    array(3) {
      [0]=>
      string(1) "1"
      [1]=>
      string(1) "2"
      [2]=>
      string(1) "3"
    }
    int(3)
