php - ErrorException : implode(): Passing glue string after array is deprecated. Swap the parameters

Question

Am running Laravel 5.8 and getting this error when seeding

Seeding: CategoriesTableSeeder

ErrorException : implode(): Passing glue string after array is deprecated. Swap the parameters

at /Users/saly/Sites/Saly/vendor/fzaninotto/faker/src/Faker/Provider/Lorem.php:95

92|         $words = static::words($nbWords);
93|         $words[0] = ucwords($words[0]);
94|
95|         return implode($words, ' ') . '.';
96|     }

The app is passing tests just fine in CI using PHP 7.3 and 7.2 so the problem might be PHP 7.4 in my local machine "OSX"

Here's my seed file

<?php

use SalyCategory;
use IlluminateDatabaseSeeder;

class CategoriesTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        factory(Category::class, 3)->create();
    }
}

And the factory

<?php

use SalyCategory;
use FakerGenerator as Faker;

$factory->define(Category::class, function (Faker $faker) {
    $name = $faker->sentence(4, true); // Here maybe?
    return [
        'name' => $name,
        'slug' => sluggify($name),
    ];
});

I think the problem is in the line where sentence() is used but I can't tell how to solve it because I just copied that line from the Faker docs

What does this error mean and how can I solve it?

Answer 1

This has already been fixed in the most recent version of Faker. In your error it says

> 95| return implode($words, ' ') . '.';

but if we look at line 95 of the source we see:

> 95| return implode(' ', $words) . '.';

So, all you need to do is pull the latest version of Faker, probably by doing

composer update fzaninotto/faker
