ATM transaction behavior with denomination of an amount in php

Php Class which can replicate ATM transaction behavior.

Assume that we have 50,000 cash available in ATM and we need to dispense money in 100,500 and 1000 rupee notes.

lets take an example if amount is 5000 then show

1000 * 4

500 * 1

100 * 5

here is my code

<html>
<body>
  <center>
    <h2>Atm Machine</h2>
    <form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">  
      <input type="text" name="txtAmount" placeholder="Enter Amount" required>
      <input type="submit" value="Submit"> 
    </form>
  <?php
    if (!empty($_POST)) {
        $message = "";
        class AtmBehavior{

          public function atmDispencer($amount){
            if($amount != ""){
              // //$amount= intval($amount);
              $notes = array(1000,500,100);
              $noteCount = array(0,0,0);
              $output="";

              if($amount <=0)
              {
                $output="<b>Invalid Amount</b>";
                return $output;
              }
              elseif ($amount > 50000) {
                 $output="<b>Amount should not exceed 50k</b>";
                 return $output;
              }
              else{
                if(!preg_match('/\d\d[0]$/',$amount))
                {
                  $output="<b>Invalid Amount</b>";
                  return $output;
                }else{
                  for($i=0;$i<count($notes);$i++){
                    if($notes[$i]<$amount || $notes[$i]==$amount){
                      $noteCount[$i]=intval($amount/$notes[$i]);
                      $amount=$amount-$noteCount[$i]*$notes[$i];
                      //$amount=$amount%$notes[$i];
                    }
                  }
                  for($i=0;$i<count($noteCount);$i++){
                    if($noteCount[$i]!=0){
                      $output .= "<br><b>".$notes[$i]." X ".$noteCount[$i]." = ".($notes[$i]*$noteCount[$i])."</b>";
                    }
                  }
                      return $output;
                }
              }
            }else{
              $output="<b>Invalid Amount- Amount Input Not Blank</b>";
              return $output;
            }
        }
    }
    $transaction = new AtmBehavior;
    $message = $transaction->atmDispencer($_POST['txtAmount']);
  ?>
  <div><br>
  <?php
    echo "Output: $message";
  }
  ?>
  </div>
</center>
</body>
</html>
