my system is CentOS 6.4 all the required extensions is installed but I don't know how to verify.

Answer 1

try to run the command :

yum install php-pecl-ssh2

Answer 2

For whatever it is worth, I tested the installation from the command line

php -i | grep ssh

and it was OK, but it did not work in a web page; took me a couple of minutes to remember I have to re-start Apache after installation :)
