Ethereum: The same webSocket code doesn’t work on another computer

Recently, I had a frustrating experience with a trading program that I copied and pasted from one computer to another, just to discover that it would not work as expected in my other car. The culprit? Monity in the WebSocket Code used by the program.

At first, I think this is a simple issue of copying and pasting the wrong code, but when I dig deeper, I realized that something more complicated is playing. It turns out that both machines use the same Websocket Library (WS4PHP), which results in an identical code, but with different addictions.

Problem:

In the automatic trade program, I had written a Websocket connection using the WS4PHP library to connect to Binance API and receive Kline’s data. However, when I copied and pasted this code in my second car (laptop), it used the same library (WS4PHP) that was installed on the older computer.

The problem was that these two computers led different versions of PHP with different libraries and configurations. This led to non -compliance with the WebSocket Code, which resulted in identical functionality, but with incorrect error processing, memory use and other problems.

Learning:

This experience taught me a valuable lesson on the importance of testing and debugging on several platforms before the code is placed in production. I needed to take a more careful approach to copying and pasting the code, ensuring that it was compatible with different machines and operating systems.

Solution:

To avoid this problem in the future, I recommend using the version of the control system, such as GIT to track changes in your web pocket library code. You can also use tools such as php -V before placing the code to test the PHP version on both computers.

In addition, consider using a more general WebSocket library that is compatible with different platforms and PHP versions. Some examples include “Websocket-Client” (which supports most major browsers and frameworks) or “Phpwebebocket”.

Conclusion:

This experience may seem like a slight failure, but it emphasizes the importance of the details when working with Websockets in complex applications. By taking steps to ensure compatibility in several platforms and PHP versions, you can avoid unsatisfactory errors and make your code more reliable.

I hope this article has given a valuable insight into the challenges of debugging a web pocket code on different computers. If you have any other questions or concerns, feel free to ask!
