merhaba php bilen yardım edebilir mi lütfen :(

https://www.r10.net/php/4363097-php-...post1088772379
burdaki konumda bxyweb in attığı kodun connect connectwauth ve execi çalışıyor sftp ile ilgili işlemler çalışmamakta hem phpseclib3 e uyarlayıp hemde
sftp işlemlerini alttakine göre yaparmısınız orjinal ssh2 eklentisi için olan kodu atıyorum
