dbx_fetch_row
(PHP 5 <= 5.0.5, PECL dbx:1.1.0)
dbx_fetch_row — Fetches rows from a query-result that had the DBX_RESULT_UNBUFFERED flag set
Описание
mixed dbx_fetch_row ( object $result_identifier )
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().
Список параметров
- result_identifier
-
A result set returned by dbx_query().
Возвращаемые значения
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).

foreach ($row as $field) {
echo "<td>$field</td>";
}
