I have a script that has to make a connection via sftp and read the contents
of a file. In the shell, I can simply type

sftp myname@remoteserver

As I use the keys on the server so don't need a password. How can I make
this connection in php so I can get the data contents nightly? We installed
teh ssh2 pecl package and I saw an example showing:


$file=fopen("ssh2.sftp://myname@remoteserver:22/files/myfile.txt","r");


Yet php throws the error that it can't find the ssh2.sftp wrapper. First,
if ssh2 installed properly is this fopen syntax correct? Second, how would
I know if ssh2 is install properly?

THanks!
