PHP Install SSH2 on Windows machine

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?

Solution 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.

Solution 2:

If anyone is having trouble installing SSH2, here's how I did it:

1) Download SSH2 PECL library from PHP.net [choose the appropriate version].

2) Copy libssh2.dll to System32 [x86] or SysWOW64 [x64] folder.

3) Copy php_ssh2.dll and php_ssh2.pdb to php/ext folder.

4) Remove ';' from the ;extension=php_ssh2.dll line in php.ini. If this line is not on your php.ini, add it.

5) Restart Apache.

Solution 3:

1. Place php_ssh2.dll in ext folder
2. Place libssh2.dll in php folder
3. Restart IIS

that work for me
