I found [url=http://php.net/manual/en/language.variables.scope.php]this[/url] in the php.net user-supplied comments

[code]
<?php
function &teleport($vars = null){
  static $toSave = array();
  if($vars){
    foreach($vars as $k=>&$v)
      $toSave[$k] = $v;
  }
  return($toSave);
}

function myFuncA(){
  extract(teleport(),EXTR_REFS);
  $a = array('a'=>1,'b'=>2);
  $b = "An arbitrary value of no consequence\n";
  teleport(array('a'=>$a,'b'=>$b));
}
function myFuncB(){
  extract(teleport(),EXTR_REFS);
  $b = "Now this is of Consequence\n";
  $c = "Another of Consequence\n";
  teleport(array('c'=>$c));
}
function myFuncC(){
  extract(teleport(),EXTR_REFS);
  // $a,$b,$c are now in current scope
  print_r(get_defined_vars());
  print_r($a);
  echo($b);
  echo($c);
}

myFuncA();
myFuncB();

myFuncC();
?> 
[/code]

Might be useful. Also of note is using "[url=http://php.net/manual/en/function.extract.php]extract[/url]" function to dump an associative array directly into the local symbol table, which simplifies what I suggested (although you probably won't want ALL of your globals dumped in that way).
