(PHP 4 >= 4.0.6, PHP 5)

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


bool dbx_sort ( object result, string user_compare_function )

如果成功则返回 TRUE,失败则返回 FALSE

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

例子 1. dbx_sort() example

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);

$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


See also dbx_compare().
