Description:
------------
When there are multiple cases within a switch block, if you try to use the header function, more specifically header("location:$url") it doesn't work. When I ran the same code under 4.3.3 it worked.

Reproduce code:
---------------
SWITCH ($_GET['method']){
  CASE 'Foo':
     //do something
  BREAK;
CASE 'Bar':
     if($i == true){
        header("location:?method=Foo")
     }else{
      //do something else  
     }
  BREAK;
}

There is parse error in your code:
you forgot to add semicolon at the end of line with Header().
This code cannot be parsed correctly neither under PHP5CVS, nor PHP4.3.3.
Having this error fixed, code works ok (but complies on undefined variables).
So, this is problem of your code.

Not a bug, but wrong syntax.

Sorry, I wrote this code quickly, trust me its got nothing to do with a parse error. It doesnt work on the Zend engine 2. I ported it back to 4.3, and it worked. I didnt change anything in the code.

SWITCH ($_GET['method']){
  CASE 'Foo':
     //do something
  BREAK;
CASE 'Bar':
     if($i == true){
        header("location:?method=Foo");
     }else{
      //do something else  
     }
  BREAK;
}

The syntax of the header() call is wrong too.

I can't find any bug here.
Passing to the script "?method=Bar" in query string and having $i equal to true it works well under PHP5-CVS.
If you get any errors here - copy/paste it and wrote a letter to php-general@lists.php.net

Trust me, there were no syntax errors. I just typed a quick example to explain what I ment.
@sniper@php.net - I even tried - header("location:http://www.google.com"); and nothing happened.

It seems the bug happens when the cases in the switch statement have quite a big chunck on code in it.

Just something to look into!
