On peut utiliser les (int) $variable (ou {$variable|intval})

<pre>{$countries|@print_r}</pre>

The @ tells smarty to pass the entire array to the modifier rather than calling the modifier for each element of the array. Smarty also ships with a modifier that does similar to print_r(): {$foo|@debug_print_var}. You may also consider smarty's debug facility (which you can enable in-template by inserting a {debug} tag or you can enable by configuring the Smarty object appropriately – see the docs for more info)
