PHP 致命错误：未捕获的错误：找不到类“SoapClient”

Question

我正在尝试在我的 Ubuntu 18.04.1 LTS VirtualBox 服务器上启用 SoapClient。
在看到我的 Soap 应用程序因 500 HTTP 错误而失败后，我参考了我的 php 错误日志并找到了以下几行：

>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

我已经尝试关注this 和其他几个人，以下是我注意到的：

在phpinfo();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，我安装了 php7.2-soap。
我究竟做错了什么？请帮忙！

Answer 1

好的，经过大量的试验和研究，我是这样解决的：

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

基本上，问题在于我的系统有两个有效版本的 PHP，并且它被配置为使用旧版本，通过这些命令你 dismod PHP7.0（禁用模块）和 enmod PHP7.2

Answer 2

首先确保你已经安装了 php 7 并且 输入并运行sudo apt list php7* 否则你可以运行sudo apt list php*

你的结果应该是这样的：

这将显示所有 php7 包。然后找到您的 soap 包并安装它。 在我的情况下，软件包是php7.2-soap，所以我将使用

安装它

sudo apt install php7.2-soap
