What are some best practices for debugging PHP scripts that are experiencing issues with server/client communication during key exchange processes?

Issue: When experiencing issues with server/client communication during key exchange processes in PHP scripts, it is important to ensure that the SSL/TLS configuration is correctly set up on the server side. Additionally, checking for any errors in the PHP code related to the key exchange process can help identify and resolve the issue. PHP Code Snippet: 

// Ensure SSL/TLS configuration is correctly set up on the server side
// Example: 
// $context = stream_context_create([
//     'ssl' => [
//         'verify_peer' => true,
//         'verify_peer_name' => true,
//         'allow_self_signed' => false
//     ]
// ]);

// Check for any errors in the PHP code related to key exchange process
// Example:
// $client = stream_socket_client('ssl://example.com:443', $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context);
// if (!$client) {
//     echo "Failed to connect: $errstr ($errno)";
// } else {
//     // Key exchange process
//     // Perform necessary operations
//     fclose($client);
// }
