retrieve array elements (smarty)

[ruthenoid]

I need to retrieve an array element in my template using smarty.
this is my array:

Code: Select all

[[assign var=foo value=$entry.extrafields.tank|explode:"|"]]


how can I get

Code: Select all

$foo[0]

?
I mean

Code: Select all

[[$foo[0]]]

does not work.
Thanx

Code: Select all

[[ $foo.0 ]]
