[PHP] Understanding system multiple steps

[Mark Steudel]

So I am using system() to try and access sftp from my php scripts. How do I
do multiple steps once I've initiated my command
 
e.g.
$file = 'filname.txt';
system( "C:\sftp\sftp.exe <login flags> | put ".$file );
 
Im on a windows box, so I don't know if I can do something like this ...
anyway any help would be ppreciated
 
THanks
