# 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 or `FALSE` on failure.

> 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);
    ?>
