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