I've heard sqlite should be built in to php5 but for some reason it wasn't.
I ran apt-get install php5-sqlite3 and successfully got phpinfo() to show:
SQLite3 support enabled
sqlite3 library version 3.3.13
However when I run sqlite_open('database.sqlite') I get:
Call to undefined function sqlite_open()
How can I find out what's wrong? Any commands to try, or logs to check?
BTW, using Ubuntu and Apache 2.2.3.
