# dbx_fetch_row

(PHP 5 < 5.1.0, PECL dbx >= 1.1.0)

dbx_fetch_row — Fetches rows from a query-result that had the `DBX_RESULT_UNBUFFERED` flag set

### 说明

dbx_fetch_row ( object `$result_identifier` ) : mixed

dbx_fetch_row() fetches rows from a result identifier that had the `DBX_RESULT_UNBUFFERED` flag set.

When the `DBX_RESULT_UNBUFFERED` is not set in the query, dbx_fetch_row() will fail as all rows have already been fetched into the results data property.

As a side effect, the rows property of the query-result object is incremented for each successful call to dbx_fetch_row().

### 参数

`result_identifier`

  A result set returned by dbx_query().

### 返回值

Returns an object on success that contains the same information as any row would have in the dbx_query() result data property, including columns accessible by index or fieldname when the flags for dbx_query() were set that way.

Upon failure, returns 0 (e.g. when no more rows are available).

### 范例

Example #1 How to handle the returned value

    <?php
    $result = dbx_query($link, 'SELECT id, parentid, description FROM table', DBX_RESULT_UNBUFFERED);

    echo "<table>\n";
    while ($row = dbx_fetch_row($result)) {
        echo "<tr>\n";
        foreach ($row as $field) {
            echo "<td>$field</td>";
        }
        echo "</tr>\n";
    }
    echo "</table>\n";
    ?>
