name ? You'll raise an Error Warning without first passing it

Only if you have error_reporting() set high. If you have a PHP templating
solution, you'd turn error_reporting() down when you included the PHP
templates so you didn't get a warning.
You assume that the PHP short-tags are enabled (? ?) for
echoing variables and while most the time they are, you shouldn't bank

short-tag echos).
You're relying on web-server writable directories when you use Smarty. It's
all a trade-off.

just mere variable substitution on it? How about highlighting all
words that match a search term, or applying logic to a display block

You can do this with output buffering and PHP functions. Smarty just
provides you a different interface.
?php start_highlight(); ?
Paragraph Text
?php end_highlight(); ?
vs.
{section type=highlight}
Paragraph Text
{/section}
Yeah, I know that's not quite the Smarty syntax, but you get the idea.
Smarty just provides an easy interface to a lot of these things. It's a
tool, like a lot of others have said. :)

This gets problematic in multi-user environments. You cant use mod_php anylonger, instead you have to switch to slow cgi+suexec. Okay, w/ metuxmpm this problem goes away - each vhost can get its own uid - but its not 100% stable yet (some rarely situations w/ recoursive requests seem to make MT problems) But what if you want to take your template and perform a bit more than just mere variable substitution on it?

Smarty just provides you a different interface. Output Buffering is a bad hack. The original branch of content-builder's base template system used this, but I've completely removed this - now there's exactly one print call at the very end of the page processing. If there have to be snippets rendered separately, it goes directly into variables or the template-engine's internal buffers (required when template processing run in a different process or host) cu -- - Enrico Weigelt== metux IT services phone: +49 36207 519931 www: http://www.metux.de/ fax: +49 36207 519932 email: [EMAIL PROTECTED] cellphone: +49 174 7066481 - -- DSL-Zugang ab 0 Euro. -- statische IP -- UUCP -- Hosting -- - -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
