I was uploading few of the modified files to my web site www.FlashWebHost.com
I found the file error_log of size 3 MB
I checked the file and found there is error due to mismatch in Zend Optimizer version.
So i upgraded the Cpanel with
# /scripts/upcp
Then install Zend Optimizer with
#/scripts/installzendopt
After installation php -v is showing Zend Optimizer.
server28# php -v
