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

91| 92|         $words = static::words($nbWords); 93|         $words[0] = ucwords($words[0]); 94| 95|         return implode($words, ' ') . '.'; 96|     } 97| 98|     /** 99|      * Generate an array of sentences 

  Exception trace:    1   implode(" ")       /Users/saly/Sites/Saly/vendor/fzaninotto/faker/src/Faker/Provider/Lorem.php:95    2   Faker\Provider\Lorem::sentence()       /Users/saly/Sites/Saly/vendor/fzaninotto/faker/src/Faker/Generator.php:222  >  Please use the argument -v to see more details. 

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

And the factory

<?php  use Saly\Category; use Faker\Generator 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
