Installing SSH2 Extension on a Windows Machine in PHP

Installing the SSH2 extension on a Windows machine with Apache requires the OpenSSL and libssh2 libraries. Here's a step-by-step guide:

1. Obtain the PHP SSH2 PECL Extension:

Download the Win32 SSH2 PECL extension from here, ensuring to select the version compatible with your PHP installation.

2. Extract and Copy Files:

Extract the contents of the downloaded archive. Copy the following files to the appropriate locations:

• Place php_ssh2.dll and php_ssh2.pdb in the PHP extension directory (e.g., C:\php\ext).
• Move libssh2.dll to both C:\Windows\system32 and C:\Windows\SysWOW64 (if you have a 64-bit Windows installation).

3. Register the DLL:

Open a command prompt as an administrator and run the following command:

C:\> regsvr32 libssh2.dll

4. Update php.ini:

Edit your php.ini file and add the following lines to enable the SSH2 extension:

extension=php_openssl.dll
extension=php_ssh2.dll

5. Restart Apache:

Restart the Apache service to load the extension.

6. Considerations for 64-bit PHP:

If you're using 64-bit PHP, you'll need to obtain the 64-bit versions of the SSH2 libraries and DLLs. Resources such as the one linked in the answer can provide these.

Additional Notes:

• Ensure you have the necessary permissions to copy and register the DLLs.
• If you encounter any issues, make sure that the PHP extension directory path is set correctly in php.ini.
• If the issue persists, verify that the OpenSSL extension is installed and functioning properly.
