<&#63;php
function msg()
{
  echo("<center><h2>Displaying even
  numbers</h2></center><p><p>");
  function displayeven()
  {
   $ctr=0;
   echo("<font size=4>");
   for($i=2;$i<=100;$i+=2)
   {
     echo("$i    ");
     $ctr++;
     if($ctr%10==0)
     {
      echo("<p>");
     }
   }
   echo("</font>");
  }
}
msg();
displayeven();
