PHP Install SSH2 on Windows machine

Question

I am trying to install this on a Windows+Apache machine. Documentation says that SSH2 requires the OpenSSL and libssh2 libraries. I have added this lines in my php.ini file:

extension=php_openssl.dll
extension=php_ssh2.dll

and restarted Apache but it still not working (Fatal error: Call to undefined function ssh2_connect()).

Can anyone explain me how to install this service?

Answer 1

Here's how I did it:

1. Downloaded Win32 SSH2 PECL extension from this location (choose the appropriate version);

2. Extracted the archive's content and:

   • placed php_ssh2.dll and php_ssh2.pdb files in the ext folder (e.g. C:\php\ext);
   • copied libssh2.dll file to C:\Windows\system32 and (if you got Win64) C:\Windows\SysWOW64 folder(s);

3. Run the following command to register the DLL:

   C:\> regsvr32 libssh2.dll
   

4. Restarted Apache.

Final note

If you got PHP x64, you have to lookup for the x64 version of the SSH2 library / DLLs. This site offers some Win64 compiled libraries for PHP, try here first.

Hope this helps.
