Thanks as a writer. I also worked with PHP 4.4.4 which is available in php.net but there is some other problem while opening go-pear.bat. I found many thread online that says php 4.3.2 is stable and perfect. But i am not able to get a link for downloading php 4.3.2 online. Do you have any idea from which website can i donwload that version of php. Thanks again for your time .
