Trying to install any recent extension using PECL fails with the error message:

Could not download from "https://pecl.php.net/get/<extension>", cannot download "pecl/<extension>" (Connection to `ssl://pecl.php.net:443' failed: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?)
Error: cannot download "pecl/<extension>"

By recent I mean after about 11 November 2018 (deduced by trying different versions of different extensions until I narrowed down the date). As far as I can tell, this affects any version of any extension for PHP 7+, with PHP downloaded from the SUSE repositories on SUSE 12 or 15. The install command is 'zypper install php7 php7-pear php7-devel'. The problem is not fixed by installing the OpenSSL package from the repos (php7-openssl). 

This does not appear to affect any other platform. It is not clear to me if this is a PHP bug or a SUSE bug.

A couple of people seem to have had this problem online, the suggested workaround is to force PECL to read php.ini when executing the PHP binary by removing the -n switch from PHP calls. See this issue: https://github.com/lazyfrosch/docker-icingaweb2/issues/1. The presence of the -n switch explains why downloading the openssl extension does not work, since that extension is loaded from an ini file.


Test script:
---------------
For example, 

pecl install decimal

Expected result:
----------------
Extension should begin to download and install.

Actual result:
--------------
