PHP7composersslrequiredforSSL/TLSprotection.

archlinux 上安装composer

$:curl -s http://getcomposer.org/installer | php

出现如下错误提示

Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:

The openssl extension is missing, which means that secure HTTPS transfers are impossible.
If possible you should enable it or recompile php with --with-openssl

于是我

$:php test.php | grep ssl

其中test.php：

得到问题所在

OpenSSL support => disabled (install ext/openssl)

现在的问题是，我要如何启用cli的ssl。php.ini中是启用了ssl，依据官方的说法，可能需要添加一个文件php-cli.ini，无果而终。

请先确认是否在安装php时安装了openssl的扩展，如果没有，请到源码etc/openssl下进行安装。环境最终是否有效以phpinfo()的结果为准，不是php.ini里配置了就会有的。
