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

### Description

bool dbx_sort ( object `$result` , string `$user_compare_function` )

Sort a result from a dbx_query() call with a custom sort function.

### Parameters

`result`

  A result set returned by dbx_query().

`user_compare_function`

  The user-defined comparison function. It must accept two arguments and return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

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);
?>`

### Notes

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