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并按照指示进行构建(而不是rpm和您拥有什么).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.

今天我需要安装此，它似乎是一个PHP库.我完成了所有步骤以进行安装，然后在$PHP_HOME/lib/extensions/somecomplicatedname/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 find ibm_db2.so in $PHP_HOME/lib/extensions/somecomplicatedname/ibm_db2.so

最重要的是，最后一步是配置php.ini，但是我的系统上没有php.ini.恐怖的恐怖. PHP可以正常工作，当然除了我要使用的这种新型ibm_db2东西外，其他人可以使用GUI修改DB2. (我尝试了一个小的php脚本，该脚本失败了，并指示ibm_db2函数不可用.)

The great catch is the last step is to configure php.ini but there is NO php.ini on my system. Horror of horrors. PHP works fine, except of course for this new-fangled ibm_db2 thingamagic 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，因此请从一个非常基本的层面上启发我，让我了解如何启用基于Web的GUI访问DB2.

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.
