A strange finding:
Today I found someone with a similar issue on the following link:
http://board.phpbuilder.com/showthread.php?10366149-RESOLVED-Executing-an-a pplication-from-PHP
It suggested to use EasyPhp. I tried with it and everything started working as desired. Thanks to Allah(subhanahu watala).
It is working whether you specify the absolute path or relative path. so doesn't seems to be a 'path' related issue.
After reading the thread mentioned above if some one can identify the real issue then it will be really worthy.
