How can PHP users ensure that their web server is properly configured for SSL connections?

To ensure that a web server is properly configured for SSL connections, PHP users can check that the server has an SSL certificate installed and that the SSL module is enabled. They can also verify that the server's configuration file includes settings for SSL protocols and cipher suites. Additionally, users can test the SSL connection using tools like OpenSSL to ensure that it is working correctly. 

// Check if SSL is enabled
if (!extension_loaded('openssl')) {
    die('SSL extension is not enabled on this server');
}

// Check if SSL certificate is installed
if (!file_exists('/etc/ssl/certs/server.crt')) {
    die('SSL certificate is missing on this server');
}

// Verify SSL configuration settings
$ssl_protocols = stream_get_transports();
if (!in_array('ssl', $ssl_protocols)) {
    die('SSL protocol is not enabled in server configuration');
}

// Test SSL connection
$ssl_test = @fsockopen('ssl://example.com', 443, $errno, $errstr, 30);
if (!$ssl_test) {
    die('SSL connection test failed: ' . $errstr);
} else {
    echo 'SSL connection test successful';
    fclose($ssl_test);
}
