Question

我已经阅读了十几个线程，但无法找出问题所在。我需要一台机器上的php5和php7，并希望php7解释一个文件夹中的脚本。我在配置中找不到错误，所以请看看

Apache：Apache / 2.4.23（Debian）

操作系统：Debian测试

安装了两个PHP版本：

nano /var/www/test/.htaccess

AddHandler application/x-httpd-php7 .php

为此文件夹设置了右AddHandler

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>
...

设置了AllowOverwrite

update-alternatives php

  Auswahl      Pfad             Priorität Status
------------------------------------------------------------
* 0            /usr/bin/php7.0   70        automatischer Modus

  2            /usr/bin/php7.0   70        manueller Modus

和php7应该是默认的anway

php -v

在命令行中可以使用

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

有什么想法吗？

Answer 1

看起来您正在使用mod_php（Server API => Apache 2.0 Handler），这意味着php作为模块嵌入在apache中。要回答这个问题，据我所知，你不能同时加载多个mod_php，这就是为什么你通过网络服务器提供的php总是第5版。

当你在命令行上使用php时，它与网络服务器无关，它根据你的更新替代品使用php7。 php命令转到/usr/bin/php7。

一种方法是使用cgi（fastcgi，php-fpm）用于不同的php版本。我还读到了通过使用不同的虚拟主机来设置它，但从未尝试过，我想这也是另一个问题。希望它有所帮助！

为什么我的脚本使用PHP5而不是PHP7
