PHP致命錯誤：未捕獲的錯誤：找不到類'SoapClient'

Question

我試圖在我的Ubuntu 18.04.1 LTS VirtualBox服務器上啟用SoapClient。
看到我的Soap應用程序因500 HTTP錯誤而失敗后，我參考了php錯誤日志並發現了以下幾行：

>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

我已經嘗試遵循此方法，並且已經嘗試了其他幾個方法，這是我注意到的：

在phpinfo（）;中 我的系統使用php7.0，但是沒有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，我已經安裝了php7.2-soap。
我究竟做錯了什么？ 請幫忙！

這將向您顯示所有php7軟件包。然后找到您的soap軟件包並安裝它。 在我的情況下，該軟件包是php7.2-soap因此我將使用

sudo apt install php7.2-soap

Answer 2

好的，經過大量的試驗和研究，這是我解決的方法：

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

基本上，問題是我的系統具有兩個有效的PHP版本，並且已配置為使用舊版本，通過這些命令，您可以將PHP7.0（禁用模塊）和PHP7.2進行修改。
