[PHP知识库]TP6开启重写模式，隐藏index.php

composer下载的TP6框架PUBLIC中.htaccess有误，必须重写这个规则才有用。

    <IfModule mod_rewrite.c>
      Options +FollowSymlinks -Multiviews
      RewriteEngine On
      RewriteCond %{REQUEST_FILENAME} !-d
      RewriteCond %{REQUEST_FILENAME} !-f
      #RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
        RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1]
    </IfModule>
