this eAccelerator included in xampp is totally bugged, won't work for me.
i have edited php.ini file (removing comment on load line) and still i get this error ->
( ! ) Fatal error: Call to undefined function eaccelerator_load() in C:\xampp\htdocs\h\index.php on line 2
of course i did restart whole xampp services after editing php.ini file so don't notice it !!!
i'm sure it's a Bug
