How to update session array in laravel 4 - updated with new items - php

Question

I'm using ajax and laravel 4 and I upload files that are arrays - they are multiple. But I'm not sure how to update session array withe the new array. I've tried array_merge but it's overwrited.
My method looks like that:
public function storeFiles() {
$name = Input::get('name');
$input = Input::all();
$current_time = time();
$trim_name = trim($name, '[]');
$corporate_docs = array();
foreach ($input[$trim_name] as $corporate) {
$file_name = $current_time . '_' . $corporate->getClientOriginalName();
$corporate->move(APPLICATIONS_DIR, $file_name);
$corporate_docs[] = $file_name;
}
$session = Session::get($name);
if($session) {
$docs = array_push($session, $corporate_docs);
Session::put($name, $docs);
} else {
Session::put($name, $corporate_docs);
}
}
How should I merge existing session array withe the newly created?
Updated: my code now is:
$trim_name = trim($name, '[]');
$corporate_docs = array();
foreach ($input[$trim_name] as $corporate) {
if ($corporate) {
$file_name = $current_time . '_' . $corporate->getClientOriginalName();
$corporate->move(APPLICATIONS_DIR, $file_name);
$corporate_docs[] = $file_name;
}
}
$session = Session::get($name);
if (Session::has($name)) {
$docs = array_merge($session, $corporate_docs); //dd($docs);
Session::forget($name);
Session::put($name, $docs); dd(Session::get($name));
} else {
Session::put($name, $corporate_docs);
}
But it is everwwriten again. When I add first image, it is stored in session and when I add another, it is merged with the first array but when I add third image, in the newly created session array - it is first image and last image. Second image is overwriten.

Try this:
if(session()->has($name)) {
session()->forget($name);
}
session()->put($name, $corporate_docs);
