Phpseclib connect MYSQL server

I want to connect to my remote MySQL server through port forwarding. Unfortunately my hosting provider don't have php_ssh2 installed on the server so I have to work through phpseclib library. So far I am able to do:

1 - Connect to server using Net_SSH2:

$ssh = new Net_SSH2('xx.xxx.xx.xx');  
 if (!$ssh->login('user', 'password')) {  
    exit('Login Failed');  
 }  

If I do echo $ssh->exec('ls -la');, it fetches directory listing telling we are connected successfully.

if I run

2 - echo $ssh->exec('echo "select * from table where company_id=\"15\";" | mysql');

It triggers:

stdin: is not a tty ERROR 1045 (28000): Access denied for user 'user'@'localhost' (using password: NO)

3 - If I do echo $ssh->exec('ssh -f -L 3307:localhost:3306 root@xx.xxx.x开发者_开发百科xx.xxx sleep 60 >> logfile');

It runs forever resulting in no response error from the server.

I am pulling my hair out. HELP!!!!!

Maybe try this?:

echo $ssh->exec('echo "select * from table where company_id=\"15\";" | mysql -u username -password=password database');

As is it's probably waiting for a password to be entered.
