how to loop in templates?

[metgharab.mestaghrab@gmail.com]

having developed this simple template engine for my own projects,the
engine simply replaces the {replacable} tags with the appropriate
value.
the template file is read into a string variable $string ,then i use
preg_replace_ca llback to process the tags.
now,i have a problem with the loops.i've though about this:

{LOOP_NAME}
things to be {repeated}
{/LOOP}

then i though about using preg_replace_ca llback twice,once to extract
the loop body,repeat it then insert it back into $string.
then use the final preg_replace_ca llback to replace all {replacable}
variables.
is this a bad idea for server loads?

I did something similar, and it took me a while to get it to work right, but I didn't have it working for long enough to get an idea of server loads. I now use Smarty template engine because it has more advanced features than I had time to make myself. It didn't seem THAT slow, but I remember wishing it were faster.
