Loading a random page in a frame

[forzatio]

Hi there, I got the info to use php random,

but I can't get it to load a random frame.

 

<?php
//Chooses a random number
$num = Rand (1,2);
//Based on the random number, gives a quote
switch ($num)
{
case 1:
<frameset rows="100%,*" border="0">
  <frame src="http://www.example.com" frameborder="0" />
  <frame frameborder="0" noresize />
</frameset>;
break;
case 2:
<frameset rows="100%,*" border="0">
  <frame src="http://www.test.com" frameborder="0" />
  <frame frameborder="0" noresize />
</frameset>;
break;

}
?>

  <frame frameborder="0" noresize />

<?php
break;
case 2:
?>
<frameset rows="100%,*" border="0">
  <frame src="http://www.test.com" frameborder="0" />
  <frame frameborder="0" noresize />
</frameset>
<?php
break;
}
?>

{

  <frame frameborder="0" noresize />
</frameset>
<?php

case 2:

<frameset rows="100%,*" border="0">
  <frame src="http://www.test.com" frameborder="0" />
  <frame frameborder="0" noresize />
</frameset>
<?php
break;
}
?>

that works , btw is this code fast to handle for the server or could it be way faster with some other code ?

<?php
$num = rand(1,2);
echo "<frameset rows=\"100%,*\" border=\"0\">\n  <frame src=\"";
switch ($num) {
case 1: echo "http://www.example.com";
break;
case 2: echo "http://www.test.com";
break;
}
echo "\" frameborder=\"0\" />\n  <frame frameborder=\"0\" noresize />\n</frameset>";
?>

 

That may be quicker.
