You can't do it that way. You might want to consider using an array.

$vars = array("test1", "test2");

foreach ($vars as $var)
   {
   echo $var . "<br/>";
   }

• OR -

$vars = array("test1", "test2");

for ($i=0; $i<sizeof($vars); $i++)
   {
   echo $vars[$i] . "<br/>";
   }

Actually, you could do it that way with variable variables. Though the array would be better.

for($i=1; $i<3; $i++) {
  $res = ${"str_".$i};
  echo $res."<br />";
}

Oops, that was a double post.

Good point, LordShryku
