yes , my problem is not about tag format , but about ideal and fastest method to parsing templates , is to use preg_replace_callback() many times ? ro use one while loop and read template line by line then parsing it ?

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 ?
