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.
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.
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.)
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.
On the command line execute:
php --ini
You will get something like:
Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File: /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
Additional .ini files parsed: /etc/php5/cli/conf.d/curl.ini,
/etc/php5/cli/conf.d/pdo.ini,
/etc/php5/cli/conf.d/pdo_sqlite.ini,
/etc/php5/cli/conf.d/sqlite.ini,
/etc/php5/cli/conf.d/sqlite3.ini,
/etc/php5/cli/conf.d/xdebug.ini,
/etc/php5/cli/conf.d/xsl.ini
That's from my local dev-machine. However, the second line is the interesting one. If there is nothing mentioned, have a look at the first one. That is the path, where PHP looks for the php.ini file.
You can grep the same information using phpinfo() in a script and call it with a browser. It’s mentioned in the first block of the output. php -i does the same for the command line, but it’s quite uncomfortable.
The best way to find this is:
Create a PHP (.php) file and add the following code:
<?php phpinfo(); ?>
and open it in a browser. It will show the file which is actually being read!

The previously accepted answer is likely to be faster and more convenient for you, but it is not always correct. See comments on that answer.
Please also note the more convenient alternative <?php echo php_ini_loaded_file(); ?> mentioned in this answer.
This works for me:
php -i | grep 'php.ini'
You should see something like:
Loaded Configuration File => /usr/local/lib/php.ini
P.S.
To get only the php.ini path, use:
php -i | grep /.+/php.ini -oE
In a command window, type
php --ini
It will show you the path something like:
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File: /usr/local/lib/php.ini
If the above command does not work then use this:
echo phpinfo();
Use the following command to find the php.ini file path on Linux.
locate php.ini
Output:
/etc/php.ini
/etc/php.ini.rpmnew
/usr/share/doc/php-common-5.4.45/php.ini-development
/usr/share/doc/php-common-5.4.45/php.ini-production
Or try this other way:
php --ini
It shows the path result.
This command should help you to find it
php -r "phpinfo();" | grep php.ini
PHP comes with two native functions to show which configuration file is loaded:
php_ini_loaded_file returns the loaded .ini file
php_ini_scanned_files returns a list of .ini files parsed from the additional ini directory
Depending on your setup, Apache and CLI might use different .ini files. Here are the two solutions:
Apache:
Just add the following in a PHP (.php) file and open it in your browser:
print php_ini_loaded_file();
print_r(php_ini_scanned_files());
CLI:
Copy-paste in your terminal:
php -r 'print php_ini_loaded_file(); print_r(php_ini_scanned_files());'
phpinfo();
will tell you its location, or from the command line
php -i
Try one of these solutions
In your terminal, type find / -name "php.ini"
In your terminal, type php -i | grep php.ini. It should show the file path as "Configuration File (php.ini) Path => /etc"
If you can access one of your PHP files, open it in a editor (Notepad) and insert phpinfo(); after <?php on a new line. This will tell you the php.ini location.
You can also talk to PHP in interactive mode. Just type php -a in the terminal and type phpinfo(); after the PHP interpreter initiated.
Run this in the command line:
php -r "echo php_ini_loaded_file().PHP_EOL;"
find / -name php.ini
Hey... it worked for me!
You can get more information about your configuration files using something like:
$ -> php -i | ack config # Use fgrep -i if you don't have ack
Configure Command => './configure' ...
Loaded Configuration File => /path/to/php.ini
For SAPI: php-fpm
There isn't any need to create a php.info file (it is not a good policy to leave it for the world to read anyway). On the command line:
php-fpm -i | more
Somewhere in its output, it will show this line:
Configuration File (php.ini) Path => /etc

according to this answer, as of PHP 7 the regular php.ini file was removed and added with php.ini-production and php.ini-devlopment.
so instead of php.ini which does not exist in my case (I've installed php 8.1), use php.ini-production and it's located in php installation folder (something like: C:\PHP-8.1.5) and create a file and name it php.ini and then copy contents of php.ini-production in this new php.ini.

In phpInfo, MAMP's Loaded Configuration File is different to the one output when running php --ini:
Loaded Configuration File: /Library/Application Support/appsolute/MAMP PRO/conf/php.ini
Even though, directly above it states the same .ini file as output in the command line:
Configuration File (php.ini) Path: /Applications/MAMP/bin/php/php5.5.10/conf
Is there a way to get MAMP to load the configuration file listed in the row Configuration File (php.ini) Path which is also output with php --ini? Or do I just have to edit the one that MAMP is using?
which php outputs that it is using MAMP's php system:
/Applications/MAMP/bin/php/php5.5.10/bin/php
One php.ini for CLI (command line) and one for web server.
Keep them separated.
If you want to change the way php behave do it depending of the context.
For cli, change the php.ini you find doing php --ini -> Loaded Configuration File
For web server change the file found when doing a phpinfo() from your browser.
I have set up PHP 5.3.10 on a RHEL 4 server.
When I ran php -i | grep "Loaded" it returned
Loaded Configuration File => (none)
It's OK with that setup. PHP is working the way we needed it to. I just need to know, if no php.ini is being used, where does PHP get all its settings? Thanks.
Update: I realized this after I hit submit. Sorry, how do I move this to Stack Overflow? -_-
Update 2: Result of php --ini:
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File: (none)
Scan for additional .ini files in: (none)
Additional .ini files parsed: (none)
If there is no php configuration file loaded it just takes the default values. Please check the documentation to have the list of the default values :
http://php.net/manual/en/ini.core.php
It may depend on your server setup.
It could be (depending on PHP version) that the PHP configuration is controlled from within the Apache configuration files:
How to change configuration settings
You can use the phpinfo() function to view your PHP configuration settings (including the config file directory). Create a file called info.php (for example in the folder that is the "DocumentRoot"), and edit the file to contain the following code:
<? phpinfo(); ?>
So, if your domain is:
http://example.com
And your "DocumentRoot" is:
".../www" or ".../public_html"
Place the file in that folder and then using a browser, go to:
http://example.com/info.php
This should show you all the settings.
First of all you got to understand that command line PHP uses another php.ini. And Apache (or NGINX etc.) module uses another php.ini.
You may try use more reliable command: php --ini rather than php -i to make sure it's not loading any configs.
Usually it loads php.ini from /etc/php5
If the command is not showing you anything, so you may try to add that file (/etc/php5/cli/php.ini) manually and check.
In RedHat it may be directly on /etc/ directory.
