    what for?
    sorry im new to this:(
    please help

    • Hi carla,

      Nice to see you here. :)

      Line creates new sqlite database in RAM, this database is just temporary. This is very useful if you have to create temporary database which work lightning fast.

      • thanks for the quick reply..
        i find your post really helpful..:)

        • You are welcome! And nice to hear that my post is helpful. :)

  4. how to apply the code on ZendFramework.. I am the beginner of Zend user…

  5. use PDO::PARAM_INT, PDO::PARAM_STR, etc instead of SQLITE3_INTEGER, SQLITE3_TEXT, etc if you only use PDO version of sqlite

  6. Thank you very much !!!! very helpful !

  7. Correct me if I’m wrong, but I think that you should make the bindValue()’s calls inside the foreach loop in order to have available the values to insert:

    foreach ( $result as $m )
    // Bind values directly to statement variables
    $stmt->bindValue( ‘:id’, $m[‘id’], PDO::PARAM_INT );
    $stmt->bindValue( ‘:title’, $m[‘title’], PDO::PARAM_STR );
    $stmt->bindValue( ‘:message’, $m[‘message’], PDO::PARAM_STR );

    // Format unix time to timestamp
    $formatted_time = date( ‘Y-m-d H:i:s’, $m[‘time’] );
    $stmt->bindValue( ‘:time’, $formatted_time, SQLITE3_TEXT );

    // Execute statement

    • Hi JavierCane,

      Maybe I miss something, but those bindValue() calls are inside foreach loop? Or did you mean bindParam() calls?

      • Yes, you’re right. I’m referring to the bindParam() calls since they use the variables $title, $message and $time which are not set in that moment.
        I really think that I’m skipping out something, but at a first sight is what I can see :-/

        • Hi again JavierCane,

          Actually bindParam calls uses reference (for second parameter $variable):

          So those variables are automatically created and assigned to null.

          I wrote quick example class to demonstrate this:

          And output is:

          Simple command line example:

          • I see JR, thanks a lot for your explanation and the detailed examples!!

  8. Thanks very interesting blog!

  9. Thank you. I knew in-memory SQLite databases were possible, but getting through’s documentation is kinda like wading thru a pool of jello sometimes. The examples are awesome! Thanks, again!

  10. I am planning to build my own CMS based on SQLITE. Till few days ago I was still working on it in sqlite2.
    You changed my mind with this example. I will switch to PDO SQLITE.

  11. Hi,

    I am attempting to get spatialite working with PDO:Sqlite. How does one load sqlite extensions with PDO? (PHP Version v5.5.9-1ubuntu4.4 pdo_sqlite v3.8.2)

    I have tried the following –

    Though it fails with –

    PHP Fatal error: Call to undefined method PDO::loadExtension()

  12. Handy little test, thanks. I had to add this just inside the opening <?php..

    // Kludges

    Also, just an observation – my initial action was to drop this into my htdocs but I needed to change the file_db to a path writable by the browser (/tmp worked for me). However, the output isn't in HTML so you might as well just run it from the command-line.

    $ php dbtest.php

    And, here's a link to download the file:

    • Thank you for this note it saved me some time figuring out what I would need to define as those constants!

  13. Thanks for this – a really helpful article!!
