PHP致命错误：未捕获的错误：找不到类'SoapClient'

Question

我试图在我的Ubuntu 18.04.1 LTS VirtualBox服务器上启用SoapClient。
看到我的Soap应用程序因500 HTTP错误而失败后，我参考了php错误日志并发现了以下几行：

>PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_soap.dll' - /usr/lib/php/20151012/php_soap.dll: cannot open shared object file: No such file or directory in Unknown on line 0 

>[Sat Jan 19 10:00:46.349246 2019] [:error] [pid 4211] [client 192.168.2.52:55730] PHP Fatal error:  Uncaught Error: Class 'SoapClient' not found in /var/www/html/sample.php:36\nStack trace:\n#0 {main}\n  thrown in /var/www/html/sample.php on line 36

我已经尝试遵循此方法，并且已经尝试了其他几个方法，这是我注意到的：

在phpinfo（）;中 我的系统使用php7.0，但是没有php7.0-soap包

 $ sudo apt-get install php7.0-soap  
Reading package lists... Done  
Building dependency tree  
Reading state information... Done  
E: Unable to locate package php7.0-soap  
E: Couldn't find any package by glob 'php7.0-soap'  
E: Couldn't find any package by regex 'php7.0-soap'  

因此，相反，我已经安装了php7.2-soap。
我究竟做错了什么？ 请帮忙！

这将向您显示所有php7软件包。然后找到您的soap软件包并安装它。 在我的情况下，该软件包是php7.2-soap因此我将使用

sudo apt install php7.2-soap

Answer 2

好的，经过大量的试验和研究，这是我解决的方法：

sudo a2dismod php7.0
sudo a2enmod php7.2
sudo systemctl restart apache2

基本上，问题是我的系统具有两个有效的PHP版本，并且已配置为使用旧版本，通过这些命令，您可以将PHP7.0（禁用模块）和PHP7.2进行修改。
