When used in a function parse_str does not appear to work
correctly.
ex:
Function test() {
   $aa = "AA1=67&AA2=89&AA3=98";
   parse_str($aa);
   echo "AA1=$AA1,AA2=$AA2,AA3=$AA3";

}
This does not work correctly. displays no values 
it worked ok in php 2
however if you do:
  echo "AA1=";
  echo $GLOBALS["AA1"];
  
it then displays the correct values.

Is this new behavior or a bug?
If new behavior it should at least be documented as this 
is a big change from version 2.
