Optimizing performance for mass-includes + Code

Hi,

I found out that mass including is very slow using php in general, e.g.
    {foreach from=$temp_table.fields key=curr_id item=item}
      {include file="asset_functions.tpl" section="item_fields"}
    {/foreach}

    {foreach from=$temp_table.fields key=curr_id item=item}
      {include file="asset_functions.tpl" section="item_data"}
    {/foreach}

this is much slower than including the code directly between the foreach 
statements.


My Solution: (based on smarty 2.6.2)

-- code can be copied without copyright hint

(increases performance with complexity of n depending on the number of n 
foreach iterations)
I create a prefilter :
The filter takes a look at the template and replaces all includes with 
the code directly (if the replaced code also has includes it works 
recursively)

$smarty->register_prefilter("modify_includes");

function replace_file($match) {
  global $smarty;
  // get the code from the included file
  if (isset($match[1]) and $match[1]!="") $result = 
modify_includes($smarty->_read_file($smarty->template_dir."/".$match[1]),$smarty);

  // map the assigned variables (using include file="" var1="value1") to 
assign
  if (isset($match[2]) and $match[2]!="") {
    while (preg_match("|(.*?)=\"(.*?)\"|i",$match[2],$var)) {
      $match[2] = str_replace($var[0],"",$match[2]);
      if (count($var)==3) {
        $result = "{assign var=\"".trim($var[1])."\" 
value=\"".$var[2]."\"}\n".$result;
      }
    }
  }
  return $result;
}

function modify_includes($tpl_source, &$smarty) {
  $tpl_source =  preg_replace_callback("|{include 
file=\"(.*?)\"(.*?)}|im","replace_file",$tpl_source);
  return $tpl_source;
}
