An array of key => value pairs of PDO attributes to pass into the PDO constructor.
For example, when using the MySQL PDO driver (opens new window), if you wanted to enable a SSL database connection
(assuming SSL is enabled in MySQL (opens new window) 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',
],
