Introduction

Bindings to the libssh2 library which provide access to resources (shell, remote exec, tunneling, file transfer) on a remote machine using a secure cryptographic transport.

Installation

Windows binaries may be found at http://snaps.php.net/. To install, download php_ssh2.dll to the folder specified by your php.ini file's extension_dir directive. Enable it by adding extension=php_ssh2.dll to your php.ini and restarting your web server.

extension_dir=c:/php5/exts/
extension=php_ssh2.dll

Linux, BSD, and other *nix variants can be compiled using the following steps:

• Download and install OpenSSL. If you install OpenSSL via your distribution's packaging system be sure to install the development libraries as well. This will typically be a package named openssl-dev, openssl_devel, or some variation thereof.

• Download and install libssh2. Typically this means executing the following command from the libssh2 source tree. ./configure && make all install.

• Run the pear installer for PECL/ssh2: pear install ssh2

• Copy ssh2.so from the directory indicated by the build process to the location specified in your php.ini file under extension_dir.

• Add extension=ssh2.so to your php.ini

• Restart your web server to reload your php.ini settings.

Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: http://pecl.php.net/package/ssh2.
