替换“//"带有“/* */"在 PHP 中? [英] Replace "//" with "/* */" in PHP?

问题描述

我正在编写代码来缩小 html/css/js，但我遇到了问题.

I'm working in a code to minify html/css/js but i got a problem.

我需要用/* 和 */替换//.

I need to replace // with /* and */.

示例:

$(funcion(){
// Do something
});

替换为:

$(funcion(){
/* Do something */
});

怎么做?

推荐答案

首先，正如评论中所指出的，如果您希望减小大小，则应删除评论.

First, as was pointed out in the comments, if you're looking to reduce the size, comments should be stripped.

function convertComment(str){
   if(str.substring(0,2) === '//'){
       str = '/*' + str.substring(2) + ' */';
   } else {
       str = false;
   }
   return str;
}

您的示例代码看起来像 JQuery，所以如果您正在寻找 PHP，这里是那个版本:

Your example code looked like JQuery, so if you were looking for PHP, here is that version:

function convertComment($s){
   if(substr($s,0,2) == '//'){
       $s = '/*' . substr($s,2) . ' */';
   } else {
       $s = false;
   }
   return $s;
}
