I'm working in both PHP and Perl. A PHP script takes various values from untrusted users and stores them in a sqlite database. Periodically, a perl script reads the sqlite database and inserts previously uninserted values into a mysql database on the other side of the internet.

I am limited in the chars I can deny to users.

Inserting into the mysql database, DBI placeholders are fine.

On the php side, sqlite_escape_string() seems to be the way to go.

Unfortunately, there does not seem to be a sqlite_udf_decode_binary() for DBI.

Right now my plan is to use base64_encode() in PHP before storing the values in sqlite and MIME::Base64 after pulling them out of the sqlite database with perl.

Better ideas ?
