Although it is certainly not a critical thing, it would be nice if
binding a table-name parameter in a PRAGMA statement worked.
executing "PRAGMA table_info (?)" produces a SYNTAX error.

Here's a quick example I came up with... it's using sqlite2 (I guess I have an
old version of php or something like that :P),
Good point Kees. I forgot about the serialize(). I don't used it because I
use my sqlite db with PHP, .NET and VB6. But if the project is going to PHP
only serialize() is the way to go.

My code is

you are delimiting your dwords wrong. reverse the byte order. this
resolves your leading and trailing 00 problem.

The easiest way to store an image would be to first convert the image to
base64 and store the base64 text to the database. Converting data to base64
