php - Flat file vs MySQL for very simple data -

from pure performance standpoint improve storing simple info (predefined messages). it's more work open file handle, json_decode "subject" , "body", , close file or query database (select subject, body predefine id='message1' assuming id primary key). have 5-10 predefined messages want assume hundreds of users may using application concurrently.

reading flat file extremely fast little files... performance advantages of databases come when effort seek specific data. if you're grabbing specific file (say, based on filename: msg_1.txt, msg_2.txt, etc) you're going improve off flatfile system.

that said, jb nizet has pointed out, if you're dealing few messages don't bother... utilize constant or create array in php file can include_once()ed when need definition:

$msg = array( 'msg1'=>array('sub'=>"subject",'body'=>"body text"), 'msg2'=>array('sub'=>"subject 2",'body'=>"body text 2"), //...etc. );

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...
