php.ini file location

Anon

I've got a question regarding the location of php.ini

I recently installed PHP4 (from source) on a REDHAT LINUX 6.2 system and was having some problems getting PHP to work using <?phpinfo () ?> in a test file. I tried a few things and then remembered that the php3.ini file had been located in "/etc/httpd" by the original REDHAT installation RPM (I had uninstalled this rpm prior to attempting the 4.x install).

So I then copied the php.ini-dist file from the PHP source directory to "/etc/httpd/php.ini" ...and things started working. However, as a result of some tests, I have now removed the php.ini file and PHP still works?

I'm wondering where PHP is getting the information it usually gets from the php.ini file?

Thanks for any help.

I think if you are using mod_php4 then the INI file is only loaded once (at apache startup). Restart apache and see if it still works. Otherwise, I'm not sure how it would be working. I assume that all of the values in the INI file have defaults it would use if it can't find the INI file. Seems like you would get a warning in one of the log files though.

From php 4.05 upwards phpinfo() will display the exact location of the php.ini file actually used.

Curious though because in testing to see which php.ini file was being used I removed every trace of it from the machine and PHP still works fine. I'm using 4.0.4pl1 and it says the php.ini file is located at /usr/local/lib but I can't find it there and yet PHP still works fine. Is it possible that PHP looks for the .ini file and uses it "if it finds it" but if it doesn't, it just uses stored primary configuration information?

Also, since this is a test machine I went through the process of of installing REDHAT, MySQL, and PHP again with the same results - PHP works, but without any php.ini file....

The bad about this is that you wuld like implement some things for example the incliude_path to use imp
and you can't do it !!!

My version was apache_1.3.14
The latest horde and the latest imp and the latest PHPLIB and I still didn't find where must I put that file.
