My first answer would be:
Don't put it in the database. Throw it in /tmp or a disk file
somewhere and put the file path into the database.
If you HAVE to put it in the database, then you'd better:
1. Determine the MAXIMUM size of the serialize($chunk) of data.
2. Double that.
3. Find a data type in your database that is BIGGER than that.
4. The only answer is probably a BLOB.
Internally, the database engine is most likely storing the BLOB as a
separate file anyway, and you're getting very very very little gain
out of putting it into the database. See first answer. :-)
