Extension mysqli is missing, phpmyadmin doesn't work
PhpMysqlPhpmyadminUbuntu 12.04Php Problem Overview
I have a problem with phpmyadmin on ubuntu 12.04. I have already installed apache2, php5, mysql and phpmyadmin.
The phpinfo(); script, don't show nothing about mysqli or mysql extension.
When I try start phpmyadmin this error appear:
phpMyAdmin - Error
The mysqli extension is missing. Please check your PHP configuration.
In the php.ini file, I uncommented extension=mysql.so line, but doesn't work...
Anyone have another posible solution?
Php Solutions
Solution 1 - Php
Latest phpMyAdmin versions require mysqli extension and will no longer work with mysql one (note the extra "i" at the end of its name).
For PHP 7.3
sudo apt-get install php7.3-mysqli
For PHP 8
sudo apt-get install php8.0-mysqli
Will install package containing both old one and the new one, so afterwards all you need to do is to add
extension=mysqli.so
in your php.ini, under the subject Dynamic Extensions.
Restart apache:
sudo systemctl restart apache2
Authenticate if needed and press enter.
Should be done! If problem still occurs remove the browser cache.
Solution 2 - Php
sudo apt-get install php5-mysql
sudo apt-get install php5-mysqlnd
try both of alternatively it works for me
Solution 3 - Php
If you run PHPMyAdmin on localhost uncomment in file /etc/php5/apache2/php.ini this line:
mysqli.allow_local_infile = On
Restart Apache:
sudo /etc/init.d/apache2 restart
Solution 4 - Php
Just restart the apache2 and mysql:
-
apache2:
sudo /etc/init.d/apache2 restart -
mysql:
sudo /etc/init.d/mysql restart
then refresh your browser, enjoy phpmyadmin :)
Solution 5 - Php
I tried a lot of the answers and none of them seemed to work because php7.0 is not the default.
sudo apt-get upgrade
seemed to do the job for me but I had to reinstall php7.0 and phpmyadmin after that:
sudo apt-get install php7.0 php7.0-mysql
sudo apt-get install apache2 apache2-mod-php7.0
sudo apt-get install phpmyadmin
Hope it helps!

I faced same issue and resolved it by doing following steps:
-
First check PHP versions. If you have multiple PHP Versions. Suppose you have PHP versions like php7.0, php7.1 and php 7.2 then
-
run these commands
For PHP7.0
sudo apt-get install php7.0-mysql
sudo apt-get install php7.0-mysqlnd
For PHP7.1
sudo apt-get install php7.1-mysql
sudo apt-get install php7.1-mysqlnd
For PHP7.2
sudo apt-get install php7.2-mysql
sudo apt-get install php7.2-mysqlnd
For PHP7.3
sudo apt-get install php7.3-mysql
sudo apt-get install php7.3-mysqlnd
3. Edit the ini file and look for mysqli. Uncomment the line by removing ; for all php versions
extension=mysqli.so
> /etc/php/<php.version>/apache2/php.ini
For PHP7.0
sudo nano /etc/php/7.0/apache2/php.ini
For PHP7.1
sudo nano /etc/php/7.1/apache2/php.ini
For PHP7.2
sudo nano /etc/php/7.2/apache2/php.ini
For PHP7.3
sudo nano /etc/php/7.3/apache2/php.ini
and last restart apache server
sudo /etc/init.d/apache2 restart
Solution 7 - Php
I solved this problem by editing /usr/local/zend/etc/php.ini.
(found it by doing netstat -nlp ¦ grep apache, then strace -p somepid ¦ grep php.ini).
At the end of the file, I added:
extension=/usr/lib/php5/20090626+lfs/mysql.so
extension=/usr/lib/php5/20090626+lfs/mysqli.so
extension=/usr/lib/php5/20090626+lfs/mcrypt.so
Adding it without the path did not work.
Then after a restart it worked.
Solution 8 - Php
For ubuntu user open your terminal and type following command
sudo apt-get install mysql
After that just restart apache2 by typing this
sudo service apache2 restart
refresh you browser and enjoy phhmyadmin
Solution 9 - Php
For Ubuntu 20.04 users with php-fpm I fixed the issue by adding the full path in the php conf:
> edit /etc/php/7.4/fpm/conf.d/20-mysqli.ini
and replace
extension=mysqli.so
with:
extension=/usr/lib/php/20190902/mysqli.so
Solution 10 - Php
Checking the extension_dir is one of the thing you like to check from phpinfo().In my case it was extension_dir = "./" by default which was wrong. Change it to extension_dir = './ext/' or where all your extension dlls are currently residing.
Solution 11 - Php
You need the MySQLi module. This error usually occurs when manually installing phpMyAdmin.
sudo apt-get install php7.3-mysql
It will return you with.
[Creating config file /etc/php/7.3/mods-available/mysqlnd.ini with new version]
[Creating config file /etc/php/7.3/mods-available/mysqli.ini with new version]
Then.
sudo service apache2 restart.
Then.
Press F5 on your browser.

This worked for me , make a database with a php and mysql script and open up the mysql console and type in create user 'yourName'@'127.0.0.1' and then type in grant all privileges on . to 'yourName'@'127.0.0.1' then open up a browser go to localhost and a database should been made and then go to your phpmyadmin page and you will see it pop up there.

Solution 14 - Php
Since I had this problem following an upgrade, I just disable Apache2-php5

and activated php7
a2enmod php7
Hope it may help anybody!
Solution 15 - Php
Just add this line to your php.ini if you are using XAMPP etc. also check if it is already there just remove ; from front of it
extension= php_mysqli.dll
and stop and start apache and MySQL it will work.
Solution 16 - Php
I have encountered the same error on ubuntu and what worked for me was editing 2 lines in /etc/php/7.3/apache2/php.ini
;extension=mysqli to extension=mysqli
and gave the extension variable location to mysqli.so after uncommenting it
extension=/usr/lib/php/20170718/mysqli.so
then restart the service just to make sure
systemctl start mysql
Solution 17 - Php
For the record, my system is Ubuntu Server 20.04 and none of the solutions here worked. For me, I installed PHP 7.4 and I had to edit enter code here /etc/php/7.4/apache2/php.ini`.
Within this, search for ;extension=mysqli, uncomment and change mysqli to mysqlnd so it should look like this extension=mysqlnd. I tried using mysqli but I faced the same error as if I didn't enable it but mysqlnd worked for me.
Solution 18 - Php
Had the very same problem, but in my case the reason was update of Ubuntu and php version - from 18.04 and php-7.2 up to 20.04 and php-7.4.
The Nginx server was the same, so in my /etc/nginx/sites-available/default was old data:
server {
location /pma {
location ~ ^/pma/(.+\.php)$ {
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
}
}
}
I could not get phpmyadmin to work with any of php.ini changes and all answers from this thread, but at some moment I had opened the /etc/nginx/sites-available/default and realised, that I still had old version of php. So I just changed it to
fastcgi_pass unix:/run/php/php7.4-fpm.sock;
and the issue was gone, phpmyadmin magically started to work without any mysqli-file complaint. I even double checked it, but yeap, that's how it works - if you have wrong version for php-fpm.sock in your nginx config file, your phpmyadmin will not work, but the shown reason will be 'The mysqli extension is missing'
Solution 19 - Php
I hope my successful answer helps someone in recent times as I had to try many mix-and-matches and then found it:
This solution worked for me on Ubuntu 20.04 Desktop with PHP v7.4, PHP v8.0.7 and MySQL v8.0.25 setup.
What I did was edited /etc/php/7.4/apache2/php.ini and /etc/php/8.0/apache2/php.ini files and replaced
extension=mysqli.so
with
extension=/usr/lib/php/20190902/mysqli.so
in both the files.
Later, restarted both of these (PHP and MySQL) by sudo systemctl restart apache2 and sudo systemctl restart mysql. Refreshed Chrome, and phpMyAdmin responded with the login screen.
(UPDATE: Please check if you have /usr/lib/php/20200930/mysqli.so file as well. I tested this as it looked newer by directory date, and this too worked in both the PHP files as extension=/usr/lib/php/20200930/mysqli.so)
