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