使用php的popen保留彩色输出 [英] Preserve colored output using php's popen

问题描述

在php中使用popen时，是否可以保留程序可能生成的彩色输出?也许我可以告诉外壳打印所有颜色转义序列，而不是解决它们的方法吗?

When using popen in php, is there a way to preserve the colored output a program might generate? Is there maybe a way I can tell the shell to print all color escape sequences, instead of resolving them?

推荐答案

这取决于您正在调用的程序.通常，如果程序支持彩色输出，则会询问操作系统我在终端上运行吗?".如果是，则输出颜色代码.如果没有，它不会.如果通过popen()运行该程序，则操作系统会说不，您不在终端上运行"，并且该程序将选择不输出颜色代码(因为它们会在捕获的输出中造成混淆).

That depends on the program you are calling. Usually, if a program supports coloured output, it would ask the OS, "am I running on a terminal?" If yes, then it outputs colour codes. If not, it won't. If you run that program through popen(), then the OS would say "no, you're not running on a terminal" and the program would choose not to output the colour codes (because they would be confusing in the captured output).

即使没有将输出写入终端，某些程序也可以选择强制输出颜色代码.但是，如果程序尚无办法，则不能在外部强制这样做.

Some programs may have an option to force the output of colour codes even if output is not being written to a terminal. However, that is not something you can force externally if the program doesn't already have a way to do it.
