SSH Connection to a remote server using PHP

Question

I want to make a SSH connection to a remote server using php.

Im using php 5.3 on Linux/CEntOS.

What I have done so far :

$connection = ssh2_connect('192.168.1.22', 22);
ssh2_auth_password($connection, '_username', '_password');
$stream = ssh2_exec($connection, 'ls -l');

But I'm getting this error :

Fatal error: Call to undefined function ssh2_connect()

So, my questions are :

Are ssh2_* functions not installed by default in php?
Do I need an extension or library for using these functions?
How can I solve this problem ?

You can configure your server (Ubuntu):

sudo apt-get install libssh2-php
sudo service apache2 restart

ssh_* function are not per default installed in php core. You have to add them using pecl, see php manual for a good description: http://de1.php.net/manual/en/ssh2.installation.php
