cubrid_fetch_array — Fetch a result row as an associative array, a numeric array, or both

### 说明

function cubrid_fetch_array(resource `$result`, int `$type` = CUBRID_BOTH): array

The cubrid_fetch_array() function is used to get a single row from the query result and returns an array. The cursor automatically moves to the next row after getting the result.

### 参数

`result`
  `Result` comes from a call to cubrid_execute()
`type`
  Array type of the fetched result CUBRID_NUM, CUBRID_ASSOC, CUBRID_BOTH. If you need to operate the lob object, you can use CUBRID_LOB.

### 返回值

Returns an array of strings that corresponds to the fetched row, when process is successful.

`false`, when there are no more rows; NULL, when process is unsuccessful.

The type of returned array depends on how type is defined. By using CUBRID_BOTH (default), you'll get an array with both associative and number indices, and you can decide which data type to use by setting the `type` argument. The `type` variable can be set to one of the following values:

- CUBRID_NUM : Numerical array (0-based)
- CUBRID_ASSOC : Associative array
- CUBRID_BOTH : Numerical & Associative array (default)

### 示例

示例 #1 cubrid_fetch_array() example

    <?php
    $conn = cubrid_connect("localhost", 33000, "demodb");
    $req = cubrid_execute($conn, "SELECT name,area,seats,address FROM stadium WHERE nation_code='GRE' AND seats > 10000");

    printf("%-40s %-10s %-6s %-20s\n", "name", "area", "seats", "address");
    while ($row = cubrid_fetch_array($req, CUBRID_NUM)) {
        printf("%-40s %-10s %-6s %-20s\n", $row[0], $row[1], $row[2], $row[3]);
    }

    // if you want to operate LOB object, you can use cubrid_fetch_array($req, CUBRID_NUM | CUBRID_LOB)

    cubrid_close_request($req);

    cubrid_disconnect($conn);
    ?>

以上示例会输出：
