Pluralization in Laravel translations

Laravel translations can depend on the number of subjects: one apple, two apples. This article will explain more complex pluralizations: no apples, one apple, two apples, tons of apples.

Define and use translations

In Laravel you can define translations in the /resources/lang/ folder. Each folder contains files with the translations for a specific language. An example of these translations:

// en/comments.php
'title' => 'Comments',

// nl/comments.php
'title' => 'Reacties',

In your views you can use these with a helper like so:


Replacing parameters

Parameters can be used in translations like so:

// en/comments.php
'number-of-comments' => ':count comments',

// in your views
trans('comments.number-of-comments', ['count' => $count])


Pluralizations give you the ability to express the difference between 1 comment and 2 comments. This time, we must use the trans_choice helper function.

// en/comments.php
'number-of-comments' => ':count comment|:count comments',

// in your views
trans_choice('comments.number-of-comments', ['count' => $count])

The downside of these pluralizations is they only define the difference between a single object and multiple objects. If we want to overcome this problem we must be specific about interval that each string belongs to.

Advanced pluralizations

Because Laravel translations are powered by the Symfony Translation component we can define even more powerful translations like this.

// en/comments.php
'number-of-comments' =>  '{0} no comments yet|{1} 1 comment|[2, Inf] :count comments',

// in your views
trans_choice('comments.number-of-comments', $count, ['count' => $count])

Each translation is a list of separated strings. Each string belongs to an interval that is denoted in the ISO 31-11 form.

A few examples of intervals:

{0}         = 0
{1,2,3}     = 1, 2, 3
[0, 3]      = 0, 1, 2, 3
]0, 3]      = 1, 2, 3
]0, 3[      = 1, 2
[-2, Inf]   = -2, -1, 0, 1, 2, ..., n
[-Inf, Inf] = -n, ..., -1, 0, 1, ..., n
