Localizable.php

TLDR

This file contains the Localizable trait, which includes a method called withLocale that allows for running a callback with a specified locale.

Methods

withLocale

This method takes a string representing a locale and a callback function as parameters. It runs the callback function with the specified locale. If no locale is provided, the callback function is executed without changing the locale. The method uses the Container class from the Illuminate\Container namespace to get the application instance and set the locale. After running the callback function, the method restores the original locale. The method returns the result of the callback function.

<?php

namespace Illuminate\Support\Traits;

use Illuminate\Container\Container;

trait Localizable
{
    /**
     * Run the callback with the given locale.
     *
     * @param  string  $locale
     * @param  \Closure  $callback
     * @return mixed
     */
    public function withLocale($locale, $callback)
    {
        if (! $locale) {
            return $callback();
        }

        $app = Container::getInstance();

        $original = $app->getLocale();

        try {
            $app->setLocale($locale);

            return $callback();
        } finally {
            $app->setLocale($original);
        }
    }
