阅读更多关于 How to prevent automatic newlines, when the output is wider than the console?

问题 I'm implementing the game of life, using console output. So far it's looking good: However, when I make the width of the output larger than the with of the console, this happens: Instead of letting the lines run offscreen, it inserts a newline. Is there a way to turn this off? I'm on a small laptop, so changing the console width doesn't really help. 回答1: I think you have to get and set the maximum length of the screen. So you get the length. If you need more space you can set the windows size

问题 I have a WIN 32 console Application which uses functionality from a 3rd party dll for which I don't have the source code.

阅读更多关于 PHP: How to use monolog to log to console (php://out)?

问题 I just switched to monolog and wanted to log my message to the PHP console instead of a file. This might seem obvious for some people, but it took me a little while to figure out how to do that and I couldn't find a similar question/answer on SO. The example on Monolog's Github readme only shows how to use a file: <?php use Monolog\Logger; use Monolog\Handler\StreamHandler; // create a log channel $log = new Logger('name'); $log->pushHandler(new StreamHandler('path/to/your.log', Logger:
