Error: file is encrypted or is not a database

Question

I used PHP to create a database with a table. I did it in the following way:

Answer 1

I recently encountered this exact same problem and have figured out what is going on. (Yes all the other answers are correct - it is a version mismatch problem.) A am posting this to provide some additional information that may be helpful to others encountering this problem...

Summary:

The error is due to the fact that the sqlite3.exe command line tool (which implements SQLite version 3), cannot read database files created using PHP's procedural interface to SQLite (which implements SQlite version 2).

Discussion:

I am following a tutorial which describes how to use SQLITE with PHP: SQLite PHP tutorial (Note that I am running PHP 5.2.14 on Windows XP). As it turns out PHP 5.2 has two (incompatible) ways of interfacing with the SQLite database management system; a procedural API (SQLite) and an object oriented API (SQLite Functions (PDO_SQLITE)). The procedural API uses SQLite version 2 and the OOP API uses SQLite version 3. For Windows PHP platforms, the procedural API is enabled by uncommenting this line in php.ini:

extension=php_sqlite.dll

While the OOP API is enabled by uncommenting these lines:

extension=php_pdo.dll
extension=php_pdo_sqlite.dll

Note that there is a free Win32 tool that allows administration and manipulation of any version of SQLite databases: SQLite Administrator. This tool allows one to convert a version 2 database (created with the procedural API of PHP) into a version 3 database that can be read using the sqlite3.exe command line tool.
