在PHP中启用mbstring扩展：未定义符号：未知，第0行的Compiler_globals

Question

我有PHP 7.1.9（从源代码编译）和mbstring：php7.1-mbstring已经是最新版本（7.1.17-0ubuntu0.17.10.1）。我在php.ini中添加了extension_dir和extension = mbstring.so。我收到消息警告：PHP启动：无法加载动态库'/usr/lib/php/20160303/mbstring.so'-/usr/lib/php/20160303/mbstring.so：未定义符号：未知行上的compiler_globals在第0行

任何人都可以建议正在发生的事情..我对php，MBstring和OS（ubuntu 16.04）的版本有些困惑

Answer 1

您可以尝试这些命令吗？

php -v

然后

php -i | grep php\.ini

只知道您是否在编辑正确的php.ini文件。您是否将apache用作您的Web服务器？您是否启用了apache的php扩展？
