Subject: [PHP] serialize
I have an app that stores evaluation scores so I have 30+ values all
within a certain range, currently in the db, each of these values has
it's own column:
Table test
id
user_id
motivation
caring
personal_characteristics
creativity,
...etc.
If the client decides they want to trap more characteristics, it
requires changes to the table structure and the table quickly gets
large with 30+ columns. I was thinking of just compacting all of
these down to one column and then using serialize/unserialize and
storing an array of the test scores....is this the best way??
Thanks!
Hi!
It doesn't seem like "good" db-practise to set all the values in one field.
You shouldn't be forced to change database-structure just because the user
inputs more information.
You may reconsider using several tables and do relations between the
tables..
