predisHow can I configure TLS encryption for a connection between PHP and Redis?

TLS encryption can be configured for a connection between PHP and Redis using the tls connection option. For example,

$redis = new Redis();
$redis->connect('127.0.0.1', 6379, null, null, null, null, [
    'tls' => [
        'ca_cert_path' => '/path/to/ca_cert.pem',
        'cert_path' => '/path/to/cert.pem',
        'key_path' => '/path/to/key.pem',
    ]
]);

The ca_cert_path option is the path to the certificate authority's certificate. The cert_path option is the path to the client's certificate. The key_path option is the path to the client's private key.

Once the connection is established, you can check the TLS encryption status using the Redis::getTlsVersion() method:

$tlsVersion = $redis->getTlsVersion();
echo $tlsVersion; // Outputs "TLSv1.2"

For more information, see the PHP Redis documentation.
