# fbsql_data_seek

(PHP 4 >= 4.0.6)

fbsql_data_seek -- Move internal result pointer

## Description

bool fbsql_data_seek ( resource result_identifier, int row_number)

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

fbsql_data_seek() moves the internal row pointer of the FrontBase result associated with the specified result identifier to point to the specified row number. The next call to fbsql_fetch_row() would return that row.

`Row_number` starts at 0.

Beispiel 1. fbsql_data_seek() example
    <?php
        $link = fbsql_pconnect ("localhost", "_SYSTEM", "secret")
            or die ("Could not connect");

        fbsql_select_db ("samp_db")
            or die ("Could not select database");

        $query = "SELECT last_name, first_name FROM friends;";
        $result = fbsql_query ($query)
            or die ("Query failed");

        # fetch rows in reverse order

        for ($i = fbsql_num_rows ($result) - 1; $i >=0; $i--) {
            if (!fbsql_data_seek ($result, $i)) {
                printf ("Cannot seek to row %d\n", $i);
                continue;
            }

            if(!($row = fbsql_fetch_object ($result)))
                continue;

            printf("%s %s<BR>\n", $row->last_name, $row->first_name);
        }

        fbsql_free_result ($result);
    ?>
