Generic table structure for storing files/images in database

What fields do you think I need to store/retrieve files generically?

I am thinking:

• name (varchar)
• data (blob)
• content_type (varchar)

Also, is there a way in php to programmatically determine content-type when file is uploaded?

(I have already asked the question files in file system or d开发者_运维百科atabase and I have chosen to go with database.)

BLOB is for store files

Depends of the app requirements but I think is not a good idea to store file in the database

I ended up going with:

• file_id (INT, auto-increment PRIMARY)
• file_name (VARCHAR 255)
• file_data(LONGBLOB)
