I have got to retrieve binary in LONGBLOB field from the db. This field is storing all sorts of file formats such as txt, doc, xdoc, pdf, etc. I basically need to be able to convert the binary format into their actual file formats in order to allow my user to download these files.
Has anyone got any idea how to do this?
As others have said, it would be best have another field to store the format. You can do this by copying the extension (ie, everything after the last “.” in the file name). The best way would probably be to get the file’s mime type: see this for example.
You can then store the mime type in a field in the database. This will almost always work, whereas the extension of a file can be misleading (or vague).
