Get multiple select data from Bootstrap Select using PHP - php

Question

I'm using bootrap-select plugin
1: https://github.com/snapappointments/bootstrap-select/ I'm trying to grab data from it. I try so many ways but it doesn't work out. So the input is like this:
<div class="col-9">
<select id="generals" name="generals" class="form-control kt-selectpicker" multiple title="Choose one of the following...">
<optgroup label="Passport">
<option value="passport_number">Number</option>
<option value="passport_date">Date of issuance</option>
<option value="passport_expired">Date of expiry</option>
<option value="passport_office">Issuing Office</option>
</optgroup>
<optgroup label="Personal">
<option value="applicant_id">Applicant Id</option>
<option value="first_name">First Name</option>
<option value="first_name">Middle Name</option>
<option value="last_name">Last Name</option>
<option value="address">Address</option>
<option value="crew_id">Crew Id</option>
<option value="email">Email</option>
<option value="mobile_number">Mobile Number</option>
</optgroup>
</select>
</div>
I try to grab using PHP foreach and for loops, implode or explode but it doesn't work since it said it does not an array. When i see the Header data sent is like this:
so how can i get this data? I'm using Ajax to send data. Here's the Fiddle if you want to see it: https://jsfiddle.net/4u6xc9kd/

It's easy, you just put the input name like this name="generals[]" in your input select and the use foreach like this:
$generals = '';
if (isset($_POST['generals'])){
foreach ($_POST['generals'] as $value){
$generals .= $value . ', ';
}
}
