Php and string analysis: how to remove comments recursively

Question

I have a string with comments in it C-style like test/* comment */ . I would like to remove them, and I would like to get this as a result: test

I've done something working, but now I would like to be able to have comment into comment, and ignore "nested comment". For example I would like to make a function that removes comments in strings like test/* co/* comment */mmen/* comment */t */ and would still return this as a result: test .

How would you do?

这是一个删除多行注释的正则表达式：

$text = preg_replace('%/\*.*?\*/%', null, $text);
