can someone help me change this to preg_replace_callback. i'm receiving the following error Warning: preg_replace_callback(): Requires argument 2, '@constant("\1")', to be a valid callback in //load current language foreach ($langs as $key => $value) if ($value['l_code'] == lang) break; $f = fopen('languages/'.$langs[$key]['l_file'],'r') or die('Cannot open language file '.$langs[$key]['l_file']); while (!feof($f)) { $s = chop(fgets($f,4096)); if ($s{0} == '#') continue; list($key,$value) = explode('=',$s,2); $value = preg_replace('/<%(.*)%>/sUe', '@constant("\\1")', $value); $def[$key] = $value; } fclose($f);

Hello , i built php class for parsing html templates , and i used preg_replace_callback function for parsing template while loops & if conditions , for loop , ... etc i repeated the function many times , for every process , such as one time for parsing while loop , and another time for if conditions parsing .. etc , and repeated all of these steps again when parsing include files inside the template , but i think that this method of parsing is slow when parsing big template , so i think that using one while loop and read template line by line and compare it then parsing found line will be more fast , so what is your opinion , using one while loop and read the template file line by line and parsing it is more useful ? or using preg_replace_callback ? and is it preferred to parse the codes inside the template ? by replacing it with php code then evaluate the template using eval() ? or parsing it inside the php file then append the result to the template ?
