./script.sh

it successfully transfer file to remote machine but when execute same script file through php it could not transfer file to remote.Any suggestions are welcome…

Answer

When you execute it in the shell you are using your user credentials.

When running from withih a PHP script script you are using apache user or group credentials.

Make sure apache can run your script
