遺憾的是php7所用的vs2015庫太新了，在win2012上都無法運行
而且，zip包里沒有所謂的php7apache2.dll ，所以還無法在apache上安裝

   Example 2-5. PHP and Apache 2.0 as CGI
ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php
 
# For PHP 4
Action application/x-httpd-php "/php/php.exe"
 
# For PHP 7
Action application/x-httpd-php "/php/php-cgi.exe"

目測手冊里說的這種安裝方式無效
