I'm building a PHP script to minify CSS/Javascript, which (obviously) involves getting rid of comments from the file. Any ideas how to do this? (Preferably, I need to get rid of /**/ and // comments)

推荐答案

在JS中删除注释的模式

Pattern for remove comments in JS

$pattern = '/((?:\/\*(?:[^*]|(?:\*+[^*\/]))*\*+\/)|(?:\/\/.*))/';

用于删除CSS中注释的模式

Pattern for remove comments in CSS

$pattern = '!/\*[^*]*\*+([^/][^*]*\*+)*/!'; 

$str = preg_replace($pattern, '', $str);

我希望以上内容能对某人有所帮助.
