Thanks all for replying. I've reinstall and now my version is 4.2.3. But I thought it comes with php_gd.dll which is not included on my phpinfo()??? However, I have that file available on my system and have done the following:
uncommented extension=php_gd.dll
set the direct. for extension_dir=C:\php
when I try to see on my phpinfo, nothing is output and the server seems to take forever to load. And guess what, when I press Ctrl + Alt + Delete, I got multiple php.exe. Any idea why??
