dbx_fetch_row

(PHP 5 <= 5.0.4)

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

Popis

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().

Seznam parametrů

result_identifier

A result set returned by dbx_query().

Návratové hodnoty

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).
