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);
?>
