On Aptible, MySQL Databases enforce SSL, but use a self-signed certificate. Here is how you can configure PHP to connect over SSL.
Using PDO
// Assuming you have set $hostname, $username, $password, $db, and $port
$url = "mysql:host=$hostname;port=$port;dbname=$db;charset=utf8";
new PDO(
$url, $username, $password,
array(
PDO::MYSQL_ATTR_SSL_CIPHER => 'DHE-RSA-AES256-SHA',
PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false
)
);
Using mysqli
// Assuming you have set $hostname, $username, $password, $db, and $port
$link = mysqli_init();
mysqli_real_connect(
$link, $hostname, $username, $password, $db, $port, NULL,
MYSQLI_CLIENT_SSL | MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT
);
