Why Can\'t I Get SSH2 to Work on My Windows Machine?

PHP: Installing SSH2 on a Windows Machine

Problem Statement:

Installing SSH2 on a Windows Apache machine seems to be problematic, despite following the documentation's instructions regarding OpenSSL and libssh2 libraries. Even after adding the required DLLs to the php.ini file and restarting Apache, the "Call to undefined function ssh2_connect()" error persists.

Installation Guide:

To successfully install SSH2 on your Windows machine, follow these steps:

1. Download SSH2 PECL Extension:

   • Visit the Win32 SSH2 PECL extension download page and select the appropriate version.

2. Extract and Place DLLs:

   • Extract the downloaded archive into a folder.
   • Copy the php_ssh2.dll and php_ssh2.pdb files to your PHP extensions folder (e.g., C:phpext).
   • Copy the libssh2.dll file to both C:Windowssystem32 and C:WindowsSysWOW64 (if you have a 64-bit system).

3. Register DLL:

   • Open a command prompt (cmd) as an administrator and run the following command:

     • C:> regsvr32 libssh2.dll

4. Restart Apache:

   • Restart your Apache web server to complete the installation.

Additional Notes:

• If you have a 64-bit PHP installation, you may need to obtain the x64 version of the SSH2 library and DLLs.
• Check online resources such as this page for pre-built Win64 libraries that support PHP.
