(PECL CUBRID >= 8.3.0)

cubrid_get — Get a column using OID

### 说明

cubrid_get ( resource `$conn_identifier` , string `$oid` [, mixed `$attr` ] ) : mixed

The cubrid_get() function is used to get the attribute of the instance of the given `oid`. You can get single attribute by using string data type for the `attr` argument, or many attributes by using array data type for the `attr` argument.

### 参数

`conn_identifier`

  Connection identifier.

`oid`

  OID of the instance that you want to read.

`attr`

  Name of the attribute that you want to read.

### 返回值

Content of the requested attribute, when process is successful; When `attr` is set with string data type, the result is returned as a string; when `attr` is set with array data type (0-based numerical array), then the result is returned in associative array. When `attr` is omitted, then all attributes are received in array form.

`FALSE` when process is unsuccessful or result is NULL (If error occurs to distinguish empty string from NULL, then it prints the warning message. You can check the error by using cubrid_error_code())

### 范例

Example #1 cubrid_get() 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);

    $attr = cubrid_get($conn, $oid, "b");
    var_dump($attr);

    $attr = cubrid_get($conn, $oid);
    var_dump($attr);

    cubrid_close_request($req);
    cubrid_disconnect($conn);
    ?>

以上例程会输出：

    string(9) "{1, 2, 3}"
    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         "
    }
