	<p>
		This is a powerful function that can process any string as a Smarty template, returning the string result.
		The way it works is quite simple. You pass the string containing the Smarty logic / variables, and a list of
		placeholders and their replacement values. It does the task of parsing the Smarty string and returning the
		result. Here's an example. Imagine your language file contained this rule:
	</p>

	{% codemirror php %}
$L["phrase_num_settings_to_complete"] = "You have {\$num_settings} settings to complete.";
	{% endcodemirror %}

	<p>
		Then, you can process that string to replace the $num_settings Smarty variable like so:
	</p>

	{% codemirror php %}
$placeholders = array("num_settings" => 5);
$string = General::evalSmartyString($L["phrase_num_settings_to_complete"], $placeholders);
echo $string; // "You have 5 settings to complete."
	{% endcodemirror %}
