Str::swap()

[khalyomede]

Hello everyone,

Recently I needed to inject a bunch of data in a string, and I really did not liked the way it looked because of all the string interpolation that made the string not easily readable.

So I thought I would bring the same "experience" we have when using trans() by replacing placeholders:

namespace App\Helpers;

use Illuminate\Support\Str as LaravelStr;

final class Str
{
    /**
     * @param array<string, string> $replace
     */
    public static function swap(string $line, array $replace): string
    {
        $newLine = $line;

        foreach ($replace as $key => $value) {
            $newLine = str_replace(
                [':' . $key, ':' . LaravelStr::upper($key), ':' . LaravelStr::ucfirst($key)],
                [$value, LaravelStr::upper($value), LaravelStr::ucfirst($value)],
                $newLine
            );
        }

        return $newLine;
    }
}

Now I can finally make my strings look nicer:

final class MemberAddedToShoppingList extends Notification
{
  public function toDatabase(): array
  {
    return [
      "message" => Str::swap(":author added you on the list :list.", [
        "author" => $this->author->name,
        "list" => $this->list->name,
      ]);
    ];
  }
}

What you guys think? Can this be useful for you? I'm eager to make a PR if you guys are interested 🤓

Why though? You can already do exactly this with __() and trans(), without needing translation files.

Does not feels legit to use translations helpers for non i18n related string manipulations for me. What you suggested works fine although.
