如何在 Centos 7 上使用 php-fpm 在 php 5.6 中添加 bcmath 扩展

如何在 Centos 7 上使用 php-fpm 在 php 5.6 中添加 bcmath 扩展

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?

php -i 输出以下配置

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

<?php
/* BC FACTORIAL
* n! = n * (n-1) * (n-2) .. 1 [eg. 5! = 5 * 4 * 3 * 2 * 1 = 120]
*/
function bcfact($n){
    $factorial=$n;
    while (--$n>1) $factorial=bcmul($factorial,$n);
    return $factorial;
}

print bcfact(50); 
//30414093201713378043612608166064768844377641568960512000000000000
