If you really want to turn all the keys of an array into variables, you can use the extract() function.

Try like this:

foreach($array as $arobj)
{
    ?>
    <li><?php $arobj['username']." with id of ".$arobj['id']; ?></li>
    <?php
}

or, if you want to assign to the variable then,

foreach($array as $arobj)
{
    $username =  $arobj['username'];
    $userid = $arobj['id'];
    ?>
    <li><?php $username." with id of ".$userid; ?></li>
    <?php
}

You can leave out the echo if you write it as <?= instead of <?php.

Just for fun, if you have to assign variables base on array key, you can try this:

foreach($array as $subArr)
{
  foreach($subArr as $key=>$value)
  {
    $$key=$value;
  }
  echo "<li>$username with id of $id.</li>";
}
