                                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)

   Returns TRUE on success or FALSE on failure.

   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.

   Example 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;
           echo $row->last_name . $row->first_name . "<br />\n";
       }
       fbsql_free_result($result);
   ?>
