A simple example of a tree transformation plugin

This PHP-compiler plugin joins together several consecutive echos into a single one and if any of the parameters to an echo is a concatenation of strings it splits them and outputs them separately. This is much faster than first concatenating strings and then outputing the whole thing. For example, this:

<?php
   echo "1" . (1 . $a ), 'ab';
   echo 'c' ,2;
   if ($a) {
      echo 2;
      //$a=1;
      echo $a;
   }
?>

is turned into this:

<?php
   echo "1", 1, $a, "abc", 2;
   if($a)
   {
      echo 2, $a;
   }
?>
