So are you saying that if I have:

That I need to change them to:

Code:
<!-- This is my comment -->
Like that?

thats all i had to do.. and it solved issues with the scripts

I played around with this a bit :)
And after talking to my co-admin (who has quite some knownledge of regular expressions) he told me to exclude <script> and other tag blocks is not possible with one RegEx, it would need additional code.

Well, so I started making some code :)

This I what I currently have, it gave me a "compression" ratio vom ~10% to ~15% in my tests, while leaving user input, [code] posts and JS fully intact (so far ;))

I added some comments, so you can see what is done where :)

PHP Code:
global $ascript, $atext, $apre;

// definition of callback functions
function cb_script($matches)
{
  global $ascript;

  $i = count($ascript) + 1;
  $h = md5($matches[0]);
  $ascript[$i][0] = $matches[0];
  $ascript[$i][1] = $h;

  return $h;
}

function cb_text($matches)
{
  global $atext;

  $i = count($atext) + 1;
  $h = md5($matches[0]);
  $atext[$i][0] = $matches[0];
  $atext[$i][1] = $h;

  return $h;
}

function cb_pre($matches)
{
  global $apre;

  $i = count($apre) + 1;
  $h = md5($matches[0]);
  $apre[$i][0] = $matches[0];
  $apre[$i][1] = $h;

  return $h;
}


// init some variables/arrays
$page_byte=strlen($output);
$ascript = array();
$atext   = array();
$apre    = array();

// cut from output, and store away for later re-inclusion, everything between <textarea> and <pre> tags
// (we do not want to touch those blocks as they may contain wanted whitespace)
$output=preg_replace_callback('/<textarea.*?[^\btextarea>\b]*?textarea>/si', "cb_text", $output);
$output=preg_replace_callback('/<pre.*?[^\bpre>\b]*?pre>/si', "cb_pre", $output);

// strip all whitespace at the beginning of every new line (but leave the linebreak intact)
$output=preg_replace('/\r\n(\s*)/', "\n", $output);

// cut from output, and store away for later re-inclusion, everthing between <script> tags
// (we don't want to strip the linebreaks from script code since that would render the scripts non working)
$output=preg_replace_callback('/<script.*?[^\bscript>\b]*?script>/si', "cb_script", $output);

// strip all linebreaks and HTML-Comments from the output
// (since we first strip all linebreaks, even multi-line comments will get striped this way! :-))
$output = str_replace( "\n" , "" , $output );
$output=preg_replace('/<!-- .*? -->/', "", $output);

// re-insert everything we saved before
foreach ( $ascript as $block)
{
  $output = str_replace( $block[1] , $block[0] , $output );
}
foreach ( $atext as $block)
{
  $output = str_replace( $block[1] , $block[0] , $output );
}
foreach ( $apre as $block)
{
  $output = str_replace( $block[1] , $block[0] , $output );
}

// calculate some nice looking numbers :-)
$pagenew_byte=strlen($output);
$page_kilobyte=number_format(($page_byte/1024),2);
$pagenew_kilobyte=number_format(($pagenew_byte/1024),2);
$pagesaved_byte=$page_byte-$pagenew_byte;
$pagesaved_kilobyte=number_format((($pagesaved_byte)/1024),2);
$pagesaved_perc=number_format(((100*$pagesaved_byte)/$page_byte),2);

// and add the compression stats at the very bottom of the page
$output = str_replace('</body>', '<center><span class="smallfont">[<em>page compression: </em>' . $pagenew_kilobyte . 'k/' . $page_kilobyte . 'k (<strong>' . $pagesaved_perc . '%</strong>)]</span></center></body>', $output);

That fixed the advanced mode bug, Hellcat, but hosed tons of other stuff on my forums. For one, the edit/quote buttons at the bottom right of posts were almost overlapped, and the breadcrumbs had no spacing at all.

A step in the right direction though, to be sure.

Screenshot attached of what I'm experiencing. I'd LOVE to get this sorted out - your code, albeit buggy on my particular theme, quadrupled my compression savings.

For reference, a screeny of my forums using my existing code, which only strips comments.

Hellcat 01-25-2006 01:49 AM
Hmm.... I think I know what that might cause....
If that's it it would reduce the ratio, but increase compatibility....
[high]* Hellcat starts tweaking :)
[/high]

[EDIT]
OK, try this:

In my above posted code, find theese two lines:
Code:
$output = str_replace( "\n" , "" , $output );
$output=preg_replace('/<!-- .*? -->/', "", $output);
and replace them by those:
Code:
$output = str_replace( "\n" , " " , $output );
$output = preg_replace('/<!--[^\{]*?-->/', "", $output);
Like I already said, this drops the ratio a bit again, but should raise compatibility.
At least I could confirm this in my last tests....

[high]* Hellcat waits for feedback now :)[/high]

does this work with vB Drupal?

Hmm, can't test that since I don't have that installed.
There's only one way to find out ;)

But it should, yes....

I'll try that right now ;)

is it supposed to take all the lines away from the source?

The Chief 01-25-2006 02:39 AM
and the result is: Nope it doesn't work with vb drupal...

works fine for my forums though so installed...

/me clicks install
