PDOException “could not discover driver”

I have just installed Debian Lenny with Apache, MySQL, and PHP and I am receiving a PDOException could not find driver.

This is the specific line of code it is referring to:

$dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASS)

DB_HOSTDB_NAMEDB_USER, and DB_PASS are constants that I have defined. It works fine on the production server (and on my previous Ubuntu Server setup).

Is this something to do with my PHP installation?

Searching the internet has not helped, all I get is experts-exchange and examples, but no solutions.

Update: newer versions should use php-sqlite3 package instead of php5-sqlite. So use this, if you are using a recent ubuntu version:

sudo apt-get install sqlite php-sqlite3

Original answer to question is here:

sudo apt-get install sqlite php5-sqlite
sudo /etc/init.d/apache2 restart

If your phpinfo() is not showing the pdo_sqlite line (in my case, on my Ubuntu Server), you just need to run the lines above and then you'll be good to go.

You need to have a module called pdo_mysql. Looking for following in phpinfo(),


PDO Driver for MySQL, client library version => 5.1.44
