如何解决PHP与openssl版本差异问题？

我尝试通过 Composer 安装 Clothing cms，但我甚至无法下载 Composer。我研究并阅读了相关资料，但还是找不到解决方案。据我所知，这很可能是 SSL 问题，特别是 PHP 的 OpenSSL。我不熟悉 PHP 也不熟悉 OpenSSL，我只是想试试 Clothing cms...

从输出中可以看出，当前安装的 openssl 版本与 php 输出的版本不同。我想这就是我的问题。我该如何纠正它并最终安装 clothes？

~$ sudo apt-cache policy openssl
openssl:
  Installed: 1.0.2k-1+deb.sury.org~trusty+5
  Candidate: 1.0.2k-1+deb.sury.org~trusty+5
  Version table:
 *** 1.0.2k-1+deb.sury.org~trusty+5 0
        500 http://ppa.launchpad.net/ondrej/php/ubuntu/ trusty/main armhf Packages
        100 /var/lib/dpkg/status
     1.0.1f-1ubuntu2.22 0
        500 http://ports.ubuntu.com/ubuntu-ports/ trusty-updates/main armhf Packages
        500 http://ports.ubuntu.com/ubuntu-ports/ trusty-security/main armhf Packages
     1.0.1f-1ubuntu2 0
        500 http://ports.ubuntu.com/ubuntu-ports/ trusty/main armhf Packages

PHP 输出：

~$ php -m | grep openssl
openssl

~$ php -i | grep OpenSSL
OpenSSL support => enabled
OpenSSL Library Version => OpenSSL 1.0.2j  26 Sep 2016
OpenSSL Header Version => OpenSSL 1.0.2j  26 Sep 2016
Native OpenSSL support => enabled

这是我尝试安装衣柜 cms 时遇到的症状：

~$ curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
All settings correct for using Composer
