Change or Replace Variable!

[Super Jinni]

it's somehow similar but not exact.
I'll try again to explain what I'm looking for.

I have a variable in one of my product. it's not an array.
this variable called $vbulletin->options['rtrf_xxx_yyy'] as it has only one value. not many values as in array.

so, I tried to use this variable in a template, in order to do that I did the following:

PHP Code:

$test=$vbulletin->options['rtrf_xxx_yyy']; 


then I put the variable $test in a template as the following:

<if condition="$test != 0">show something</if>

but nothing showed up.

then I tried using the following code:

<if condition="$vbulletin->options['rtrf_xxx_yyy'] != 0"> show something</if>

and it worked just fine as I want it.

then I tried to put only $test variable in the template to see if it gonna show up. but it didn't.

I -then- put $vbulletin->options['rtrf_xxx_yyy'] and it shows me Array['rtrf_xxx_yyy']


then I put {} around the variable like this {$vbulletin->options['rtrf_xxx_yyy']} and it works fine and showes me what I want.

I'm just wondering why it did not work when I use $test but work fine when I use {$vbulletin->options['rtrf_xxx_yyy']} although I already set $test value as I mentioned above. $test=$vbulletin->options['rtrf_xxx_yyy'];

what I want exactly is to use $test in the template instead of $vbulletin->options['rtrf_xxx_yyy']. but I couldn't make it work or show up.
