通常 ANSI 代码是由 ESC (\033 aka \x1b) 引入的，一个空心方块括号，然后是数字(可能重复:*[32;40m)并以字母结尾.

Usually ANSI codes are introduced by an ESC (\033 aka \x1b), an open square bracket, then numbers (possibly repeated: *[32;40m) and terminated by a letter.

你可以使用类似 #\\x1b[[][0-9]+(;[0-9]*)[A-Za-z]# 到 preg_replace 他们都被遗忘了.

You can use something like #\\x1b[[][0-9]+(;[0-9]*)[A-Za-z]# to preg_replace them all to oblivion.

这有效(刚刚测试)，即使绝对是矫枉过正:

This works (just tested), even if definitely overkill:

$test = preg_replace('#\\x1b[[][^A-Za-z]*[A-Za-z]#', '', $test);

我也在 GitHub 上找到了这个，和 此内容一>.

I've also found this on GitHub, and this on SO.
