Use array_filter in foreach

Question

I am presenting this problem when making a store in my database, which is data entered from a table in my view.

Example: table

For example, my user selects row 1 and 4 in which he fills in the data and that is sent to the controller to be stored, the problem arises when filtering the values ​​of the select and input columns.

values ​​that the table sends: values

I need to store the values ​​of the rows, for example 1 and 4, filtering the empty values ​​that the user has not filled or selected

This is my view:

<table id="example4" class="display min-w850">
                            <thead>
                                <tr>
                                    <th style="text-align: center;vertical-align: middle">Seleccionar</th>
                                    <th style="text-align: center;vertical-align: middle">Software</th>
                                    <th style="text-align: center;vertical-align: middle">Marca</th>
                                    <th style="text-align: center;vertical-align: middle">Nombre de Version</th>
                                    <th style="text-align: center;vertical-align: middle"> # Version</th>
                                    <th style="text-align: center;vertical-align: middle">Tipo de venta</th>
                                    <th style="text-align: center;vertical-align: middle">Observación</th>


                                </tr>
                            </thead>
                            <tbody>

                                    <tr>
                                        <td style="text-align: center;vertical-align: middle">
                                            <input type="checkbox" name="id_version[]" value="{{ $cli->id_version }}">
                                        </td>

                                                autocomplete="off">

                                    </tr>
                                @endforeach
                            </tbody>

                        </table>

this is my controller:

$checked_array = $request->input('id_version');
   // $obs_software = ($request->input('obs_software'));
 
    foreach ($_POST['id_version'] as $key => $value) 
    {       
        if (in_array($_POST['id_version'][$key], $checked_array)[$key])
       
        {                                        
                        $soft_instal = new Software_instalacion;
                        $soft_instal->id_instalacion             = $instalaciones->id;
                        $soft_instal->id_historial               = $historial->id;
                        $soft_instal->id_usuario                 = $request->id_usuario;
                        $soft_instal->id_version                 = $request->input('id_version')[$key];
                        $soft_instal->obs_software               = $request->input('obs_software')[$key];
                        $soft_instal->id_tipo_venta              = $request->input('id_tipo_venta')[$key];
                        $soft_instal->save();
                       
        }                         
     }
