dbx_sort

(PHP 4 >= 4.0.6)

dbx_sort -- Sort a result from a dbx_query by a custom sort function

Description

bool dbx_sort ( object result, string user_compare_function)

Returns TRUE on success, FALSE on error.

Note: It is always better to use ORDER BY SQL clause instead of dbx_sort(), if possible.

Example 1. dbx_sort() example

<?php
function user_re_order ($a, $b) {
 $rv = dbx_compare ($a, $b, "parentid", DBX_CMP_DESC);
 if ( !$rv ) {
 $rv = dbx_compare ($a, $b, "id", DBX_CMP_NUMBER);
 }
 return $rv;
}
$link = dbx_connect (DBX_ODBC, "", "db", "username", "password")
 or die ("Could not connect");
$result = dbx_query ($link, "SELECT id, parentid, description FROM tbl ORDER BY id");
 // data in $result is now ordered by id
dbx_sort ($result, "user_re_order");
 // data in $result is now ordered by parentid (descending), then by id
dbx_close ($link);
?>
