This is my best result, following the first post and searching many sites, this function well works for javascript and css and html content in php

function _compress($html){
   //remove comments
   $html = preg_replace('|(?:(?:\/\*(?:[^*]|(?:\*+[^*\/]))*\*+\/)|(?:(?<!\:)\/\/.*))|', '', $html ); //Yancharuk's code/regex

   // remove tabs, spaces, newlines, etc.
   $html = str_replace(array(PHP_EOL, "\t"), '', $html);

   //remove all spaces
   $html = preg_replace('|\s\s+|', ' ', $html);

   return $html;
}
