An array of key => value pairs of PDO attributes to pass into the PDO constructor.

For example, when using the MySQL PDO driver, if you wanted to enable a SSL database connection (assuming SSL is enabled in MySQL and 'user' can connect via SSL, you’d set these:

[
    PDO::MYSQL_ATTR_SSL_KEY    => '/path/to/my/client-key.pem',
    PDO::MYSQL_ATTR_SSL_CERT   => '/path/to/my/client-cert.pem',
    PDO::MYSQL_ATTR_SSL_CA     => '/path/to/my/ca-cert.pem',
],
