Problem
You want to retrieve a translation string that is different depending on a count.
Solution
Use the Lang::choice() method.
In addition to the key you must also pass the number.
echo Lang::choice('message.items', 1);
Your language file should have at least two messages for the key, separated by the pipe (|) character.
'items' => "There's just one item|You've got multiple items",
Like the Lang::get() method, you can specify place holders with an additional array argument.
echo Lang::choice('message.items', 3, ['type' => 'widget']);
This would replace any :type in the string with the word widget. Note that the :count placeholder is automatically set.
Adding a fourth argument allows you to specify the locale instead of using the default locale.
echo Lange::choice('message.items', 2, [], 'es');
Discussion
You can have more than two messages based on the count.
The default is two: the first message when the count is 1, the second when the count is anything other than 1, but the following translation has three different messages.
'items' => "{0} There's none|[1,3] Just a few|[4,Inf] A bunch",
