Sort a result from a dbx_query by a custom sort function
Descriptionbool 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);
?>
