为什么我的脚本使用PHP5而不是PHP7

我已经阅读了十几个线程，但无法找出问题所在。我需要php5和php7在一台机器上，并希望在一个文件夹中的脚本被php7解释。我在配置中找不到错误，所以请查看

Apache: Apache/2.4.23 (Debian)

OS: Debian Testing

两个PHP版本都已安装:

/var/www/test# ls -l /usr/bin/php*
lrwxrwxrwx 1 root root      21 Okt  6  2015 /usr/bin/php -> /etc/alternatives/php
-rwxr-xr-x 1 root root 9065192 Jul 26 10:33 /usr/bin/php5
-rwxr-xr-x 1 root root 4422704 Sep 18 10:38 /usr/bin/php7.0
lrwxrwxrwx 1 root root      28 Okt  6  2015 /usr/bin/php-config -> /etc/alternatives/php-config
-rwxr-xr-x 1 root root    5237 Jul 26 10:33 /usr/bin/php-config5
lrwxrwxrwx 1 root root      24 Okt  6  2015 /usr/bin/phpize -> /etc/alternatives/phpize
-rwxr-xr-x 1 root root    4730 Jul 26 10:33 /usr/bin/phpize5

为这个文件夹设置了右AddHandler

nano /var/www/test/.htaccess
AddHandler application/x-httpd-php7 .php

设置AllowOverwrite

nano /etc/apache2/apache2.conf
...
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow 
# access here, or in any related virtual host.
<Directory />
        Options FollowSymLinks
        AllowOverride None
        Require all denied
</Directory>
<Directory /usr/share>
        AllowOverride None
        Require all granted
</Directory>
<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>
...

和php7应该是默认的

update-alternatives php
  Auswahl      Pfad             Priorität Status
------------------------------------------------------------
* 0            /usr/bin/php7.0   70        automatischer Modus
  1            /usr/bin/php5     50        manueller Modus
  2            /usr/bin/php7.0   70        manueller Modus

命令行

php -v

但不在服务器上下文中!

w3m http://localhost/test/info.php

任何想法?
