secure shell tunneling - which php version/functions to use?

[Fehnris]

Hi there,

I have a question regarding php/mysql and ssh. 

I hope im in the right place to ask this.  Well, here goes. 

My question is does anyone know the best way to create a ssh tunnel using only PHP and then being able to use that tunnel to connect securely to a remote MYSQL database? 

This procedure has been driving me loopy trying to figure out a way to do it.  Ive found various library functions as part the PHP language but the information ive found on them, tends to be abit vague with a lack of working examples.

I hope there is someone out there that has already had experience with this and can offer some help.

Thanks in advance.
