php - sanitizing a string before serializing and inserting to db -

i'm facing odd problem....

$string user input

$log = serialize(array('string' => $string);

example: "test" be

"string";s:4:"test";

however problems arise when user submits quotes , other characters ; of course of study escape string first, serialized info cannot unserialized.

htmlentities before submitting db wouldn't work either since ; messes data...

any suggestions?

please don't tell me create db fields , not utilize serialize()

i not sure if best practice quick hack using : http://php.net/manual/en/function.base64-encode.php , http://www.php.net/manual/en/function.base64-decode.php encrypt info when sending db , decrypting when retrieve it. if think there might security issues encrypting using base64 here link in improve way : best way utilize php encrypt , decrypt?

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...
