Smarty Object Function with Associative Array Unexpected “=>”, expected one of: “”,“” , “)”'-Collection of common programming errors

I am having a problem with Smarty passing a PDO Object to Smarty it just doesn’t like =>. Is there a trick to get around this problem?

Here is he error:

{assign var='brgdatas' value="{$brgObj->fetchOneBrg(array('id'=>{$ststres[ststval].to_id}'))}"}" - Unexpected "=>", expected one of: "","" , ")

Here is the code I am working with:

{section name=ststval loop=$ststres}

{if $ststres[ststval].type == 2}

{assign var='brgdatas' value="{$brgObj->fetchOneBrg(array('id'=>{$ststres[ststval].to_id}'))}"}

The correct answer Update:

Is to add [] between the associative array and remove the quotes like so.

{assign var='brgdatas' value=$brgObj->fetchOneBrg(['id'=>$ststres[ststval].to_id])}
