Forums.php is the normal index.php that vb has but i had renamed it and i have index the cmps.

The thing is that the code in the file is fine.... even though i had replaced it with the latest and i still getting the error.

I had also uninstalled the addon with no luck...... I am with IIS6 .. php 4.4.6 with apc and mysql 4.1.16.

Anyone has any clue?

Are you using the experimental version?

Sorry, what do you mean?

You don't need any vBulletin modification to run APC/aAccelerator/xcache.

Place the function in a file & create forums/cache folder

function cache_templates_one_file($templates, $templateidlist)
{
	global $vbulletin, $templateassoc;

	if (empty($templateassoc))
	{
		$templateassoc = unserialize($templateidlist);
	}

	if ($vbulletin->options['legacypostbit'] AND in_array('postbit', $templates))
	{
		$templateassoc['postbit'] = $templateassoc['postbit_legacy'];
	}
	
	foreach ($templates AS $template)
	{
		$templateids[] = intval($templateassoc["$template"]);
	}

	/* THE ACTUAL PLUGIN */
	$templatefile = 'cache/'.md5(implode(',', $templateids)).'.php';
	if (file_exists($templatefile))
	{
		include($templatefile);
	}
	else
	{
		$templatecache = '';
	/* END ACTUAL PLUGIN */
		// run query
		$temps = $vbulletin->db->query_read("
			SELECT templateid, title, template
			FROM " . TABLE_PREFIX . "template
			WHERE templateid IN (" . implode(',', $templateids) . ")");
		// cache templates
		while ($temp = $vbulletin->db->fetch_array($temps))
		{
			/* START ACTUAL PLUGIN */
			preg_match_all('/\$[a-zA-Z][a-zA-Z\_0-9]+/', $temp['template'], $out);
			$vars = array_unique($out[0]);
			$templatecache .= '
				/* '.$temp['title'].' */ $template_vars['.$temp['templateid'].'] = \''.implode(', ', $vars).'\'; function template_'.$temp['templateid'].'('.implode(', ', $vars).') { return "'.$temp['template'].'"; } ';
			/* END ACTUAL PLUGIN */
		}
		$vbulletin->db->free_result($temps);
		/* START ACTUAL PLUGIN */
		$fp = fopen($templatefile, 'w+');
		if ($fp && flock($fp, LOCK_EX))
		{
			fwrite($fp, '<?php '.$templatecache.' ?>');
			flock($fp, LOCK_UN);
			fclose($fp);
		}
		include($templatefile);
		/* END ACTUAL PLUGIN */
	}

	foreach ($templates AS $template)
	{
		if (substr($template, 0, 17) == 'editor_jsoptions_' or substr($template, 0, 14) == 'editor_styles_')
		{
			$vbulletin->templatecache[$template] = call_user_func('template_'.intval($templateassoc["$template"]));
		}
		else $vbulletin->templatecache[$template] = '".template_'.intval($templateassoc["$template"]).'('.$template_vars[intval($templateassoc["$template"])].')."';
		#$vbulletin->templatecache[$template] = '';
	}
	
	$vbulletin->bbcode_style = array(
		'code'  => &$templateassoc['bbcode_code_styleid'],
		'html'  => &$templateassoc['bbcode_html_styleid'],
		'php'   => &$templateassoc['bbcode_php_styleid'],
		'quote' => &$templateassoc['bbcode_quote_styleid']
	);
}

And call it in "cache_templates" hook (adjust the path for the file with the function in it)

include('includes/functions_hooks.php');
cache_templates_one_file($globaltemplates, $style['templatelist']);
$globaltemplates = array();

does not delete cache when modifying templates and no options in it, please

ONLY USE THIS IF YOU KNOW WHAT YOU ARE DOING and understand the code

It basically reads all templates and creates a function for every template with all the variables in it passed as arguments so you can avoid scope issues.

Please note this takes up A LOT of space in xcache/APC (about 40mb for the cache/ files alone) so make sure you have enough space allocated (I'm using 128mb atm and that works fine).

Again please don't install this if you don't know PHP well and know what you're doing. Just sharing this because I've been using it for a few days successfully and maybe somebody can use it. This mod doesn't modify the database or any vB files (like the version you can download).

Orban,could u please help a bit more about it...

[orban]

I just don't have the time right now to support this thing (I mean check the number of pages in this thread, and the experimental is indeed experimental and there's several issues to be worked out).

[Zia]

ah ha..Okay..
just thought it might be good than the existing one...so wanted to give a try....

Okay....but like this existing mods "boost up php cache" for any opcode cacher...
is there any way to boost up var.cacher ?
