activation of libssh2 to internal php interpreter

dear community,

is there a way, to install and activate the libssh2 library to the integrated php interpreter of phprunner? (in detail: $ apt-get install libssh2-1-dev
$ pecl install -a ssh2-1.3)

I want to use some sftp features (get and put of files from/to a remote server) which needs this library. see here: https://sftptogo.com/blog/php-sftp/

in my productive environment with access of the php configurations the sftp features are already working, but I want to test it during development on my local machine with the phprunner instance.

thank you
Helmut
