Extremely easy to set up and very noticable rewards even on an empty cache. Thanks! Oh this piece of code has been godsend to me.

I rewrote the algorithm as My solution was incomplete (remove comments, tabs, spaces, newlines, etc):

compress_page($buffer) {
$search = array(
“/ +/” => ” “,
“/<!–\{(.*?)\}–>|<!–(.*?)–>|[\t\r\n]|<!–|–>|\/\/ <!–|\/\/ –>|<!\[CDATA\[|\/\/ \]\]>|\]\]>|\/\/\]\]>|\/\/<!\[CDATA\[/" => ""
);
$buffer = preg_replace(array_keys($search), array_values($search), $buffer);
return $buffer;

}

this compresses all html, and javaScript but not CSS for this I use:

compress_styles($buffer) {
// remove comments, tabs, spaces, newlines, etc.
$search = array(
"/\/\*(.*?)\*\/|[\t\r\n]/s” => “”,
“/ +\{ +|\{ +| +\{/” => “{“,
“/ +\} +|\} +| +\}/” => “}”,
“/ +: +|: +| +:/” => “:”,
“/ +; +|; +| +;/” => “;”,
“/ +, +|, +| +,/” => “,”
);
$buffer = preg_replace(array_keys($search), array_values($search), $buffer);
return $buffer;

}

Hope this is useful to someone.

If it's just the removal of the newlines, I don't believe that it will be enough to say that the same conclusion as the study I pointed to doesn't apply here.The removal of human-dedicated characters is not interesting when digging out to optimize performances because (a) there's too little to win for normal size webpages, and (b) the gzip compression make advantage of the redundance of these special characters and thus compress the page effisciently enough. @Nouman: what is “way further” exactly?

This script makes it like the google source code where the files is compressed way further than what html tidy can do @ loius as I said that was done using html tidy which doesnt do what this script does, unless Im mistaken.

Your PHP code "gets rid of tabs, line breaks, and extra spaces", and as I initially pointed out, that is not a relevant thing to do to optimize loading times and co. @Nouman: I don’t understand your remark.
