php - Multidimensional array sort on multiple keys -

hi i've been using array_sort() function found here time sort results multiple apis have need sort 2 keys simultaneously.

the 2 keys need sort on deal_score desc , date_start desc

the properties of array follows. record 2 has highest deal_score should come first records 0 , 1 have same deal_score date_start higher on record 1 final order of results should 2, 1, 0

here's illustration array has been trimmed downwards readability.

[0] => array ( [db_id] => 414314 [date_start] => 2012-04-17 [deal_score] => 81.3 [deal_statements] => array ( [0] => 49.85 [1] => 2.11 ) ) [1] => array ( [db_id] => 414409 [date_start] => 2012-04-20 [deal_score] => 81.3 [deal_statements] => array ( [0] => 28.2 [1] => 21.41 ) ) [2] => array ( [db_id] => 1345923 [date_start] => 2012-04-17 [deal_score] => 85 [deal_statements] => array ( [0] => 18.1 [1] => 22.16 ) )

any help on appreciated.

sth. should do:

foreach ($data $key => $row) { $score[$key] = $row['deal_score']; $dates[$key] = $row['date_start']; } array_multisort($score, sort_asc, $dates, sort_asc, $data);

3rd. illustration on http://php.net/manual/en/function.array-multisort.php pretty much explains it.

cheers.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
