Ok guys, what is going wrong here? I checked this for 20 times, and still get an error.

<?php

function hello($arr){
  if(is_array($arr)){
    foreach ($$arr as $name){
      echo "Hello, $name!";

    }

  } else {
    echo 'Hello, friends';
  }
  echo "Hello, $name!</br>";
}
$names = array('Vule', 'Jole', 'Car')
hello($names);

U used a double $ in your foreach loop. => foreach ($arr as $name){ ... }
