/**
|
|
* WordPress Filesystem Class for implementing SSH2
|
|
*
|
|
* To use this class you must follow these steps for PHP 5.2.6+
|
|
*
|
|
* @contrib http://kevin.vanzonneveld.net/techblog/article/make_ssh_connections_with_php/ - Installation Notes
|
|
*
|
|
* Compile libssh2 (Note: Only 0.14 is officaly working with PHP 5.2.6+ right now, But many users have found the latest versions work)
|
|
*
|
|
* cd /usr/src
|
|
* wget https://www.libssh2.org/download/libssh2-0.14.tar.gz
|
|
* tar -zxvf libssh2-0.14.tar.gz
|
|
* cd libssh2-0.14/
|
|
* ./configure
|
|
* make all install
|
|
*
|
|
* Note: Do not leave the directory yet!
|
|
*
|
|
* Enter: pecl install -f ssh2
|
|
*
|
|
* Copy the ssh.so file it creates to your PHP Module Directory.
|
|
* Open up your PHP.INI file and look for where extensions are placed.
|
|
* Add in your PHP.ini file: extension=ssh2.so
|
|
*
|
|
* Restart Apache!
|
|
* Check phpinfo() streams to confirm that: ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2.sftp exist.
|
|
*
|
|
* Note: As of WordPress 2.8, this utilises the PHP5+ function `stream_get_contents()`.
