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);
?> |
