What are some best practices for handling socket operations in PHP, especially when dealing with potential errors like "ENOTSOCK"?

When handling socket operations in PHP, it's important to properly check for potential errors like "ENOTSOCK" which indicates that the file descriptor does not refer to a socket. To handle this error, you can use try-catch blocks to catch any exceptions that may arise during socket operations and handle them accordingly. 

try {
    // Perform socket operations here
} catch (Exception $e) {
    if ($e->getCode() === SOCKET_ENOTSOCK) {
        // Handle ENOTSOCK error here
        echo "Error: Not a socket";
    } else {
        // Handle other socket errors
        echo "Socket error: " . $e->getMessage();
    }
}
