ovrimos_fetch_into

(PHP 4 >= 4.0.3)

ovrimos_fetch_into -- Fetches a row from the result set

Description

bool ovrimos_fetch_into ( int result_id, array result_array [, string how [, int rownumber]])

ovrimos_fetch_into() fetches a row from the result set into result_array, which should be passed by reference. Which row is fetched is determined by the two last parameters. how is one of Next (default), Prev, First, Last, Absolute, corresponding to forward direction from current position, backward direction from current position, forward direction from the start, backward direction from the end and absolute position from the start (essentially equivalent to 'first' but needs 'rownumber'). Case is not significant. rownumber is optional except for absolute positioning. 如果成功则返回 TRUE,失败则返回 FALSE

"Connection ok!";
    
$res=ovrimos_exec($conn, "select table_id, table_name from sys.tables");
    if (
$res != 0) {
        echo
"Statement ok!";
        if (
ovrimos_fetch_into($res, &$row)) {
            list(
$table_id, $table_name) = $row;
            echo
"table_id=" . $table_id . ", table_name=" . $table_name . "\n";
            if (
ovrimos_fetch_into($res, &$row)) {
                list(
$table_id, $table_name) = $row;
                echo
"table_id=" . $table_id . ", table_name=" . $table_name . "\n";
            } else {
                echo
"Next: error\n";
            }
        } else {
            echo
"First: error\n";
        }
        
ovrimos_free_result($res);
    }
    
ovrimos_close($conn);
}
