我在哪里可以找到 php.ini? [英] Where can I find php.ini?

问题描述

几年前，我在自己维护的 Linux 服务器上安装了 Apache 2.2x 和 PHP 5.3.1.我使用 .tar.gz's 并按照说明构建它们(而不是 rpms 和 what-have-you).一切都很好.

A few years ago I installed Apache 2.2x and PHP 5.3.1 on a Linux server I maintain. I used .tar.gz's and built them as instructed (instead of rpms and what-have-you). And all was fine.

今天我需要安装这个，它看起来像一个 PHP 库.我完成了安装的所有步骤，我在 $PHP_HOME/lib/extensions/somecomplicatedname/ibm_db2.so 中找到了 ibm_db2.so.

Today I need to install this which seems like a PHP library. I went through all the steps up to make install, and I found ibm_db2.so in $PHP_HOME/lib/extensions/somecomplicatedname/ibm_db2.so.

最大的收获是最后一步是配置文件php.ini，但没有any php.ini 文件在我的系统上.恐怖的恐怖.PHP 工作正常，当然除了我想使用的这个新奇的 ibm_db2 thingamajig 之外，这样有人可以使用 GUI 来修改 DB2.(我尝试了一个小的 PHP 脚本，该脚本失败并表明 ibm_db2 函数不可用.)

The great catch is the last step is to configure file php.ini, but there aren't any php.ini files on my system. Horror of horrors. PHP works fine, except of course for this newfangled ibm_db2 thingamajig that I want to use so somebody can use a GUI to tinker with DB2. (I tried a small PHP script which fails and indicates that the ibm_db2 functions are not available.)

我必须每隔几年处理一次 PHP，所以请从一个非常基本的层面告诉我我可以做些什么来启用对 DB2 的基于 Web 的 GUI 访问.

I have to deal with PHP once every few years, so please enlighten me at a very basic level about what I could do to enable web-based GUI access to DB2.

推荐答案

找到这个的最好方法是:

The best way to find this is:

创建一个 PHP (.php) 文件并添加以下代码:

Create a PHP (.php) file and add the following code:

<?php phpinfo(); ?>

并在浏览器中打开它.它将显示实际正在读取的文件！

and open it in a browser. It will show the file which is actually being read!
