As there are multiple versions of PHP with different sever configurations, php.ini could be located in several different folders.

Method 1

One way to find out exactly which

<?php
phpinfo();
?>

2 file your web sever is using is by creating a new PHP file in document root called

<?php
phpinfo();
?>

3.

info.php

<?php
phpinfo();
?>

Load this file in your browser, press

<?php
phpinfo();
?>

4 +

<?php
phpinfo();
?>

5 (or

<?php
phpinfo();
?>

6 +

<?php
phpinfo();
?>

5 on Mac) and search for “Loaded Configuration File”. You should see something like

/etc/php/8.1/apache2/php.ini

This will tell you the exact location of the php.ini file you want to edit.

Method 2

In Linux, run this command to locate the

<?php
phpinfo();
?>

8 configuration file.

php -i | grep "Loaded Configuration File"

Or in Windows Command Line:

php -i | findstr /c:"Loaded Configuration File"

The result should be something like this:

Loaded Configuration File => /etc/php/8.1/cli/php.ini

In the above example, we can see that the PHP install is located in

<?php
phpinfo();
?>

9. Note that there are three different configuration files you should we aware of:

CLI

/etc/php/8.1/apache2/php.ini

0 is for the CLI PHP program. Changes to this config file will only affect PHP as it runs in the terminal – it will NOT affect the web server.

Apache

/etc/php/8.1/apache2/php.ini

1 is for the PHP plugin used by Apache. This is the one you need to edit if you are using the Apache web server.

Nginx or Apache with PHP-FPM

/etc/php/8.1/apache2/php.ini

2 is a fastcgi-compatible ‘wrapper’ for PHP processing. This is the one you need to edit if you’re using the Nginx web server or Apache with PHP-FPM.

Method 3

Using the

/etc/php/8.1/apache2/php.ini

3 command in Linux,. If it’s not already installed, run

/etc/php/8.1/apache2/php.ini

4.

You should see a list of php.ini files here. Try editing one of them and restarting you web server to see if makes the required changes.

Editing php.ini in Linux

Apache

On Apache,

<?php
phpinfo();
?>

2 is usually located in

/etc/php/8.1/apache2/php.ini

1. Replace

/etc/php/8.1/apache2/php.ini

7 with your own version, e.g,

/etc/php/8.1/apache2/php.ini

8,

/etc/php/8.1/apache2/php.ini

9, etc.

To edit:

sudo nano /etc/php/8.1/apache2/php.ini

However, if you are using PHP FPM, it may be located in

/etc/php/8.1/apache2/php.ini

2. Replace

/etc/php/8.1/apache2/php.ini

7 with your own version, e.g,

/etc/php/8.1/apache2/php.ini

8,

/etc/php/8.1/apache2/php.ini

9, etc.

To edit:

sudo nano /etc/php/8.1/fpm/php.ini

To save file and exit, press

<?php
phpinfo();
?>

4 +

php -i | grep "Loaded Configuration File"

5, press

php -i | grep "Loaded Configuration File"

6 and then press

php -i | grep "Loaded Configuration File"

7

You must restart Apache after altering

<?php
phpinfo();
?>

2.

sudo systemctl restart apache2

If you are using PHP-FPM, you must restart that service. Replace

php -i | grep "Loaded Configuration File"

9 with your own version, e.g,

/etc/php/8.1/apache2/php.ini

8,

/etc/php/8.1/apache2/php.ini

9, etc.

sudo service php8.1-fpm restart

Nginx or Apache with PHP-FPM

Nginx uses PHP FPM and <code>php.ini</code> is usually located in <code>/etc/php/8.1/fpm/php.ini</code>. Replace <code>8.1</code> with your own version, e.g, <code>php5.6</code>, <code>php7.4</code>, etc.</p><div class="code-wrap"><pre id="supercoder-block_629f3eb9c73bc" class="code language-bash"><code class="language-bash">sudo nano /etc/php/8.1/fpm/php.ini</code></pre><div class="btn-copy-wrapper"><button class="btn-copy" title="Copy"></button></div></div><p>Save and exit (press <code>CTRL</code> + <code>X</code>, press <code>Y</code> and then press <code>ENTER</code>)</p><p>You must restart Nginx after altering <code>php.ini</code>.</p><div class="code-wrap"><pre id="supercoder-block_629f3ed8c73bd" class="code language-bash"><code class="language-bash">sudo systemctl reload nginx</code></pre><div class="btn-copy-wrapper"><button class="btn-copy" title="Copy"></button></div></div><a class="anchor" id="id-older-versions"></a><h2>Older Versions</h2><p>For versions of Ubuntu <em>lower</em> than 16.04, <code>/etc/php/5.6/</code>,<code>/etc/php/7.0/</code>,<code>/etc/php/7.1/</code>, and so on, are replaced by <code>/etc/php5/</code> and so on.
