我正在尝试在安装了 PHP 5.6 以及 nginx 和 php-fpm 的 Centos 7 上添加 bcmath 扩展
我运行了以下步骤并安装了 bcmath 扩展
yum install php56-bcmath
上面安装了 bcmath 扩展，我可以在 phpinfo() 输出中的“模块”列下看到它。
但是当我调用 php 函数时获取已加载的扩展，我没有在加载的扩展列表中看到 bcmath。
安装 bcmath 包后，我重新启动了 php-fpm 和 nginx。
我是否遗漏了什么？

答案1
我找到了问题所在。
我安装了多个 PHP
还安装了 php56 版本，该版本由 php-fpm 使用。因此，我使用以下命令安装了 bcmath 库，然后将其应用于正确的 PHP 安装。
yum install php56-php-bcmath
重新启动 php-fpm，问题解决。
答案2
它安装了吗？ 尝试使用它....我以为 bcmath 自 5.6 起就包含在 php-fpm 中
