php 5.6 (5.5?) ssh2_connect unavailable (2 replies)

Hi,
I tried installing the ssh2 extension with PHP 5.6 but it is failing.

[04-Feb-2019 16:18:04 UTC] PHP Warning: PHP Startup: ssh2: Unable to initialize module
Module compiled with module API=20121212
PHP compiled with module API=20131226
These options need to match
in Unknown on line 0

The version I downloaded was for php 5.5 on this page: [pecl.php.net]
because there was no php 5.6 version.

If this is the reason why it is not working, then how can I get php 5.5 on wamp or find a ssh2 version that works with php 5.6.35

I'm on WAMP 3.1.3
Thanks for responding.
