how to remove the last two commas in an array after using the implode function

I am trying to remove the last two commmas of an array using the trim function but can't get it to work....Is my syntax correct?

I have tried to use the trim function after imploding the array into a string

if(isset($_POST['doctors'])) {
$doctors = $_POST['doctors'];
$doctors = implode(', ', $doctors);
$doctors = strip_tags($doctors);
$doctors = trim($doctors);
} else {
  $doctors = 'Not Supplied';
}

I also used rtrim but still can't remove the last commas... I will also include my form html, just in case I did something wrong there:

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
 <div class="medical_form">
    <div class="medical_form_title">
    <h2>Submit a Review of a Medical Clinic</h2>
 </div>
   <form class="medical_form" action="medical_review_process.php" method="POST">

I have 3 doctors input but users can only type just one and if they typed just one doctor, I would like to remove the last two commas:

You can try it 

rtrim(',',$doctors);

There are two possibilities as far as I can see.

trim() only removes spaces, so to trim commas as well you need to add what characters it should trim (commas and spaces in this example)...

$doctors = trim($doctors, ", ");

Or you could remove empty entries from the array before implodeing it using array_filter()...

$doctors = array_filter($_POST['doctors']);
