Laravel array_merge(): Argument #2 is not an array In ServiceProvider.php

Question

I can not do php artisan serve anymore, it says :

In ServiceProvider.php line 59:
   array_merge(): Argument #2 is not an array

Line 59 code is in ServiceProvider.php:

$this->app['config']->set($key, array_merge(require $path, $config));

I dont understand what is wrong with my ServiceProvider.php, I did not change a thing there.

I hope some can help me.

Is this from `laravel/framework/src/Illuminate/Support/ServiceProvider.php`? Wouldn't change anything there. Check if all your config files are valid — brombeer, Dec 18 '18 at 08:53

Check the files in your config/ folder, one of them is not returning an array.

try this one

used is_array method here.

$this->app['config']->set($key, array_merge(require $path, is_array($config) ? $config : [$config]))

is_array($config) ? $config : [$config]

if do not want change on framework file check configration files in your config folder one the file return single value not an array (must be return array)

Don't make any change in that file. The problem is surely somewhere else. Read the error message carefully, see the log and add the errors in your question. – Rouhollah Mazarei Dec 18 '18 at 08:59
It worked! thanks a lot, I had to generate a key after. But it worked! – slekniws Dec 18 '18 at 09:14

I recommend to _NOT_ edit the file `laravel/framework/src/Illuminate/Support/ServiceProvider.php`, this is a Laravel core file and might/will be overwritten on the next composer update - all your modifications will be lost. – brombeer Dec 18 '18 at 10:10

Try this,

Any new installation via Composer for some package may cause a conflict in file under vendor.

So remove the lastly installed package via "composer.json" in "require": { } and update the composer.

This helped me.

This works for me. first, edit the code laravel/framework/src/Illuminate/Support/ServiceProvider.php

if (! ($this->app instanceof CachesConfiguration && $this->app->configurationIsCached())) {
        $config = $this->app->make('config');
        
        $configkey = $config->get($key, []);
        $configkey = is_array($configkey) ? $configkey : [$configkey];

        $config->set($key, array_merge(
            require $path, $configkey
        ));

    }

save it. and run composer install.
