我有一个案例，我不小心开始解压我的文件目录在根。它从我的文件文件夹中添加了。htaccess文件，这将阻止所有php

# If we know how to do it safely, disable the PHP engine entirely.
<IfModule mod_php5.c>
  php_flag engine off
</IfModule>

底线检查根目录下的.htaccess文件。

在尝试了以上所有方法都没有效果之后，考虑重新启动你的电脑。解决了我的。

对于运行php 7的LAMP的新设置 编辑/etc/httpd/conf/httpd.conf文件 注意:在更改任何内容之前，请确保对其进行备份。

把这个粘贴在文件的最底部:

<IfModule php7_module>
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>

然后，搜索LoadModule并粘贴以下行:

LoadModule php7_module modules/libphp7.so

这一行将简单地要求httpd加载php 7模块

然后重启httpd

听起来你的配置好像有问题，下面是一些你可以检查的东西:

Make sure that PHP is installed and running correctly. This may sound silly, but you never know. An easy way to check is to run php -v from a command line and see if returns version information or any errors. Make sure that the PHP module is listed and uncommented inside of your Apache's httpd.conf This should be something like LoadModule php5_module "c:/php/php5apache2_2.dll" in the file. Search for LoadModule php, and make sure that there is no comment (;) in front of it. Make sure that Apache's httpd.conf file has the PHP MIME type in it. This should be something like AddType application/x-httpd-php .php. This tells Apache to run .php files as PHP. Search for AddType, and then make sure there is an entry for PHP, and that it is uncommented. Make sure your file has the .php extension on it, or whichever extension specified in the MIME definition in point #3, otherwise it will not be executed as PHP. Make sure you are not using short tags in the PHP file (<?), these are not enabled on all servers by default and their use is discouraged. Use <?php instead (or enable short tags in your php.ini with short_open_tag=On if you have code that relies on them). Make sure you are accessing your file over your webserver using an URL like http://localhost/file.php not via local file access file://localhost/www/file.php

最后，查看PHP手册以获得更多的设置技巧。

如果你有这样的配置:

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot "/var/www/example.com"

    <FilesMatch "\.php$">
        SetHandler "proxy:fcgi://127.0.0.1:9000"
    </FilesMatch>
</VirtualHost>

取消httpd.conf中的下几行注释

LoadModule proxy_module lib/httpd/modules/mod_proxy.so
LoadModule proxy_fcgi_module lib/httpd/modules/mod_proxy_fcgi.so

这对我很有用

在尝试了所有方法之后，我想出了这个解决方案

当默认情况下PHP 7.0 FPM未启用时，将出现此错误。

要在Apache2中启用PHP 7.0 FPM，运行:

 sudo 2enmod proxy_fcgi setenvif
 sudo a2enconf php7.0-fpm
 systemctl restart apache2

如果您使用的是php7.4，在上面的命令中输入7.4而不是7.0。
