Because you're injecting variables directly into your HTML, which some
of the time might be ok - but what if the $row_array doesn't contain
"name" ? You'll raise an Error Warning without first passing it
through some kind of test (or function).
You assume that the PHP short-tags are enabled (<? ?>) for
echoing variables and while most the time they are, you shouldn't bank
on it in code (incidentally, you don't need the trailing ; on the
short-tag echos).
Sure - these things can be fixed easily, but then that isn't the point
- if you think about it logically, anything Smarty can do, PHP can do
too (well, duh! :)
But what if you want to take your template and perform a bit more than
just mere variable substitution on it? How about highlighting all
words that match a search term, or applying logic to a display block
based on a user status?
Personally I don't use smarty*, but even I can see the benefits it
offers.
* only because I don't build web sites for clients, I build them for
one specific company and we have our own template system in-house.
