AppExtension.php

<?php

namespace App\Twig;

use Twig\Extension\AbstractExtension;
use Twig\TwigFilter;

class AppExtension extends AbstractExtension
{
  public function getFilters(): array
  {
    return [
      new TwigFilter('pluralize', [$this, 'pluralize'])
    ];
  }

  public function pluralize(int $count, string $singular, string $plural, string $zero = null): string
  {
    if ($count > 1){
      return str_replace('{}', $count, $plural);
    } else if ($count <= 0 && null !== $zero){
      return $zero; // No string replacement required for zero
    }
    return str_replace('{}', $count, $singular);
  }
}

Ok. In French the plural is only if the value is > 1 (and I'm french ^^).

• 0 pomme
• 1 pomme
• 2 pommes
• 3 pommes

You can adjust it easily if you need to change the rule.

Thank you for the work you did. It's pretty much what I'm looking for. Merci!
