Alternative $this->config>set_item($item, $value) - simonickalexs - 12-01-2019
I notice that this function is not in CI4. But, I need this function to dynamically inject (temporary) array string to public $item = [] from \Config\App.php. Is there any alternative or maybe there's a workaround I'm not noticing?
Thank you!

All the config files are classes where all the properties are public. That means that once you create an instance of a config you can modify the properties however you see fit.
PHP Code:
<?php namespace App\Controllers;
use Config;
class Home extends BaseController
{
public function index()
{
$viewConfig = new Config\View();
$viewConfig->saveData = false;
// do stuff
}
}
You can dynamically add properties to the class
PHP Code:
$config = new Config\App();
$config->adHoc = ["Hello ", "World", "!"];
foreach ($viewConfig->adHoc as $value)
{
echo $value; // Hello World!
}

Thanks for the reply. It seems that it didn't work to push array to my public $item = [...];. Here's my code:
app\config\Packages
PHP Code:
<?php namespace Config;
use CodeIgniter\Config\BaseConfig;
class Packages extends BaseConfig
{
public $footer_js = ['nuxt.js', 'jquery.js', 'idk.js'];
// ......
}
app\Controllers\Test
PHP Code:
<?php namespace App\Controllers;
class Test extends BaseController
{
public function index()
{
$ci = new \Config\Packages();
$ci->footer_js = 'vue.js';
foreach($ci->footer_js as $v)
{
echo $v;
echo '<br/>';
}
The output should show nuxt.js, jquery.js, idk.js, and vue.js. But instead, it just show only vue.js.
In real case, I really want to dynamically add Javascript files to footer page. I have this helper works on CI3, but I'm still confused how can I make it work on CI4-rc. Thank you!

At this point you have discovered the error, but I only make the comment for those of us who come to this post for one reason or another and we do not see a conclusion.
Obviously the error is that you are replacing the Scripts array with a single value, instead you can use array_push
PHP Code:
$ci = new \Config\Packages();
array_push($ci->footer_js, 'vue.js');

$ci->footer_js[] = 'vue.js';
