Just want to check if it is possible to edit/update a data when my database is save the data like this:

I want to update the school_name, start_date, end_date, qualification_list all those but I don't know how. Previously I did an update and it was successfull but the style inside is different:

Can anyone give me any tips or what to do to be able to update the data for the first screenshot? Thanks in advance.
Previously I update my data like this:
public function update1(Request $request, $user_id){
$object2 = qualification::find($user_id);
$test = array();
$test['School'] = implode(' , ', $request->School);
$test['SDate'] = implode(' , ', $request->SDate);
$test['EDate'] = implode(' , ', $request->EDate);
$test['qualification'] = implode(' , ', $request->qualification);
$object2->update($test);
return redirect('/home');
}
But how do I update the data now based on the first screenshot?
$idof the multiple rows? How to distinguish schools? Byuser_id?$object2 = qualification::find($id);This line implies$idisidof the table, not theuser_id??
