PHP PDO exception: could not find driver

问题

Does the MySQL-server and PHP5-MySQLi version have to match in order for a connection to be possible? I'm currently receiving the error below: I am running BSD. "Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'..."

Here is the the connection info:

$info = "mysql:dbname=myDB;host=localhost";
$user = "dbUser";
$pw = "somePW";
return(new PDO($info, $user, $pw));

Here is my MySQL information:

mysql-server-5.5.24

php5-mysqli-5.4.3

PDO uses database specific drivers to connect to database systems. It looks like you are missing the pdo_mysql driver that is required to connect to a MySQL database. There is some details on installing the driver on the pdo_mysql manual page, or there may be a BSD package that you can use (I am afraid I'm not familiar enough with BSD to offer specific advice).

I had this same issue on my CentOS install. I had tried to install imagick and hosed my install. When I removed all of my php files and reinstalled something wasn't working right.

I ran:

yum install php-pdo
yum install php-pdo_mysql

After doing those two lines I ran

service httpd restart

and everything came back up and running.

Thanks to zerkms and John C for pointing me in the right direction. Below are the commands I used to install the driver:

#cd /usr/ports/databases/php5-pdo_mysql
#make install clean
#apachectl restart
