For Windows, you can find the file in the C:\xampp\php\php.ini
-Folder (Windows) or in the etc
-Folder (within the xampp-Folder).
Under Linux, most distributions put lampp under /opt/lampp
, so the file can be found under /opt/lampp/etc/php.ini
.
It can be edited using a normal Text-Editor.
Clarification:
Xampp
(X (for "some OS"), Apache, MySQL, Perl, PHP)Lampp
(Linux, Apache, MySQL, Perl, PHP)
in this context, they can be substituted for one another.

Only with xampp on windows it is the \xampp\php folder – Matijs May 31 '11 at 09:13

/etc/ deosn't have a xampp folder – Jonathan Feb 13 '15 at 05:49

/opt/lampp/etc/php.ini – Jonathan Feb 13 '15 at 05:50

1@JonathanLeaders yeah, that's under4 Linux. I meant the `etc`-folder *within* the xampp/lampp folder. – Lukas Knuth Feb 13 '15 at 13:39
Write the following inside phpini_path.php
( or AnyNameAsYouLike.php
) and run it in the browser.
<?php phpinfo();?>
Among various other parameters you'll get Loaded Configuration File
parameter which value is the path of php.ini
on the server.
The location of php.ini
depends on server operating system:
Windows (With Xampp Installation):
/xampp/php/php.ini
macOS, OS X:
/private/etc/php.ini
Linux:
/etc/php.ini
/usr/bin/php5/bin/php.ini
/etc/php/php.ini
/etc/php5/apache2/php.ini

If you have multiple php-versions (xampp etc) running, I find the easiest is to use:
php --ini
from the command line. In windows: either after you click Shell
in xampp, or directly in the regular cmd
to find the "global" version of php. With global I mean the version referenced to by your environment variables.

Run Xampp server.
Go to http://localhost which will open up xampp dashboard.
Go to PHPInfo link in the top navigation bar.
--- or directly type following url in the browser after run the XAMPP http://localhost/dashboard/phpinfo.php
This will open up php info page. There you can find "Loaded Configuration File /opt/lampp/etc/php.ini" which is the php.ini location.

Thanks I have also installed xampp and found the php.ini in the above path that you mentioned :) – Arzon Barua Sep 20 '20 at 09:38
Put a script somewhere in your document root
<?php
phpinfo();
Among others the output of the function will tell you which php.ini
s are parsed before the script got executed.

I've always found the easiest way is php -i
and filtering down.
*nix (including MacOS):
php -i | grep "Loaded Configuration File"
Windows:
php -i | findstr /C:"Loaded Configuration File"
Of course this assumes your CLI environment is using the same PHP binaries as your actual web server.
You can always check that to be sure using which php
in *nix and where php
in Windows.

so, what do I do if in OSX there's no php.ini ? php -i | grep "Loaded Configuration File" ✔ at 06:32:21 PM Loaded Configuration File => (none) – Mona Jalal Jun 26 '22 at 22:39

@MonaJalal: Then you do not have an ini file. Solution (in my case): `sudo cp /etc/php.ini.default /etc/php.ini` – Luuk Jan 29 '23 at 10:23
-
@MonaJalal `sudo find / -type f -name "php.ini"` should help you (this will search the whole drive which could be slow, a more localized search would be faster like `find /etc -type f -name "php.ini"` for instance) – Yes Barry Jan 31 '23 at 16:10
This is one of those "you were technically accurate, but you didn't answer my question" but it doesn't mean the above were wrong or misguided - they just didn't run into my issue.
So, I figure I'll give an answer.
As the others mentioned (spot on), I created a file:
<?php
phpinfo();
?>
So that worked great. However, it showed "(none)"
So where do you find (none)!?
In my case, on Windows, you just go to where php is installed; I had already had installed it in c:\php
I believe it would be the same steps on other platforms.
Then, from a command line, powershell for ex, type: notepad c:\php\php.ini
Tell it yes, you do want to create it, then add whatever changes you needed in the first place. For me, for example:
extension_dir = "c:\php\ext"
extension=mysqli
upload_max_filesize = 25M
post_max_size = 13M
max_execution_time = 300
Then save. Fixed!
By the way - if you do "file new" and then "save as" Notepad will helpfully rename your file to php.ini.txt. Friends let friends NOT AVOID THE CLI.

This feels like an entirely different question and answer posted as an answer to a nine year old question. If you remove it here, but separate it into a question and an answer you can post the question and self answer it and increase both the quality of the site and your chances of getting an upvote. – Jason Aller Aug 18 '20 at 18:04

If you have been using different installers, you may well end up with more that one php.ini file on your hdd, which could affect your sanity after a while.
Search your hdd for 'php.ini' just in case there is more than one.
Another sanity-saving move is to remember to always restart your server (apache) after altering a value in php.ini.

as KingCrunch pointed out, using phpinfo you can see what config file is in action in the "Loaded Configuration File" row. in my case in was in C:\xampp\apache\bin note that there is a php.ini also in C:\xampp\php which seems to be redundant and irrelevant

In the documentation http://www.apachefriends.org/en/xampp-windows.html (Configuration files section, near the bottom of the page): \xampp\php\php.ini
