mysqli_use_result mysqli->use_result Initiate a result set retrieval Procedural style: mixedmysqli_use_result objectlink Object oriented style (method): mysqli mixed use_result void mysqli_use_result is used to initiate the retrieval of a result set from the last query executed using the mysqli_real_query function on the database connection specified by the link parameter. Either this or the mysqli_store_result function must be called before the results of a query can be retrieved, and one or the other must be called to prevent the next query on that database connection from failing. The mysqli_use_result function does not transfer the entire result set from the database and hence cannot be used functions such as mysqli_data_seek to move to a particular row within the set. To use this functionality, the result set must be stored using mysqli_store_result. One should not use mysqli_use_result if a lot of processing on the client side is performed, since this will tie up the server and prevent other threads from updating any tables from which the data is being fetched. Returns an unbuffered result object or &false; if an error occured. mysqli_real_query, mysqli_store_result. multi_query($query)) { do { /* store first result set */ if ($result = $mysqli->use_result()) { while ($row = $result->fetch_row()) { printf("%s\n", $row[0]); } $result->close(); } /* print divider */ if ($mysqli->more_results()) { printf("-----------------\n"); } } while ($mysqli->next_result()); } /* close connection */ $mysqli->close(); ?> ]]> ]]> The above examples would produce the following output:
