> Smarty will recognize <A

<A

embedded in double quotes so long as the variable name contains only numbers,
letters, underscores and brackets[]
(see <A
HREF="http://php.net/language.variables"
TARGET="_top"
>naming</A
>).
With any other characters (period,
object reference, etc.) the variable must be surrounded by
`backticks`. You cannot embed
<A
HREF="language.modifiers.html"
>modifiers</A
>, they must always
be applied outside of quotes.

>SYNTAX EXAMPLES:
{func var="test $foo test"} <-- sees $foo
{func var="test $foo_bar test"} <-- sees $foo_bar
{func var="test $foo[0] test"} <-- sees $foo[0]
{func var="test $foo[bar] test"} <-- sees $foo[bar]
{func var="test $foo.bar test"} <-- sees $foo (not $foo.bar)
{func var="test `$foo.bar` test"} <-- sees $foo.bar
{func var="test `$foo.bar` test"|escape} <-- modifiers outside quotes!
PRACTICAL EXAMPLES:
{include file="subdir/$tpl_name.tpl"} <-- will replace $tpl_name with value
{cycle values="one,two,`$smarty.config.myval`"} <-- must have backticks</PRE
