(PECL CUBRID >= 8.3.1)
cubrid_fetch_field — 從結果集中取得欄位資訊並以物件形式返回
此函式會返回一個物件，其中包含特定欄位的某些屬性。物件的屬性如下：
name欄位名稱
table欄位所屬的表格名稱
def欄位的預設值
max_length欄位的最大長度
not_null如果欄位不可為 NULL，則為 1
primary_key如果欄位是主鍵，則為 1
unique_key如果欄位是唯一鍵，則為 1
multiple_key如果欄位是非唯一鍵，則為 1
numeric若欄位為數值類型則為 1
blob若欄位為 BLOB 類型則為 1
type欄位的類型
unsigned若欄位為無號數類型則為 1
zerofill若欄位為零填充則為 1
resultresult 來自呼叫 cubrid_execute() 的結果
field_offset數值欄位偏移量。如果未指定欄位偏移量，則會擷取下一個（尚未由此函式擷取的）欄位。field_offset 從 0 開始。

<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$req = cubrid_execute($conn, "SELECT event_code,athlete_code,nation_code,game_date FROM game WHERE host_year=1988 and event_code=20001;");
var_dump(cubrid_fetch_row($req));
cubrid_field_seek($req, 1);
$field = cubrid_fetch_field($req);
printf("\n--- Field Properties ---\n");
printf("%-30s %s\n", "name:", $field->name);
printf("%-30s %s\n", "table:", $field->table);
