Streams allow you to use PHP streams as a template resource or a variable resource. The syntax is much the same a traditional template resource names.
Smarty will first look for a registered template resource. If nothing is found, it will check if a PHP stream is available. If a stream is available, Smarty will use it to fetch the template.
Note
You can further define allowed streams with security enabled.
Example 213. Stream from PHP
Using a PHP stream for a template resource from the display() function.
$smarty->display('foo:bar.tpl');
Example 214. Stream from Template
Using a PHP stream for a template resource from within a template.
{include file="foo:bar.tpl"}
You can also use streams to call variables. {$foo:bar} will use the foo://bar stream to get the template variable.
Example 215. Stream Variable
Using a PHP stream for a template variable resource from within a template.
{$foo:bar}
