Ошибка расширение mysqli для php не установлено

I know this is a while ago but I encountered this and followed the other answers here but to no avail, I found the solution via this question (Stackoverflow Question)

Essentially just needed to edit the php.ini file (mine was found at c:xamppphpphp.ini) and uncomment these lines…

;extension=php_mysql.dll
;extension=php_mysqli.dll
;extension=php_pdo_mysql.dll

After restarting apache all was working as expected.

This article can help you Configuring PHP with MySQL for Apache 2 or IIS in Windows. Look at the section «Configure PHP and MySQL under Apache 2», point 3:

extension_dir = "c:phpextensions"      ; FOR PHP 4 ONLY 
extension_dir = "c:phpext"             ; FOR PHP 5 ONLY

You must uncomment extension_dir param line and set it to absolute path to the PHP extensions directory.

I had the same problem and I solved it. You can solve it too if you follow these steps:

1. you have to install PHP to C:/php
   or your current version locate it to this path and specify it as a system variable

2. then open xampp program and click config and open php.ini
   and uncomment the following lines:

   extension=pdo_mysql
   extension=pdo_mysql
   extension=openssl
   

try to change PHP version

$sudo update-alternatives --config php

if it didn’t work
change for example from PHP 5.6 => PHP 7.1

    $ sudo a2dismod php5.6
    $ sudo a2enmod php7.1  
    $ sudo service apache2 restart

I encountered this problem today and eventually I realize it was the comment on the line before the mysql dll’s that was causing the problem.

This is what you should have in php.ini by default for PHP 5.5.16:

;extension=php_exif.dll       Must be after mbstring as it depends on it
;extension=php_mysql.dll
;extension=php_mysqli.dll

Besides removing the semi-colons, you also need to delete the line of comment that came after php_exif.dll. This leaves you with

extension=php_exif.dll      
extension=php_mysql.dll
extension=php_mysqli.dll

This solves the problem in my case.

Its an issue of extension directory. You need to change php extension directory manually to work this.

If you are using AMPP Server, do the following

Goto settings -> PHP -> Configuration

in php7.3.ini Find, (Versions might change)

extension_dir = «» , (Already having some path)

and change value to

extension_dir = «C:Program FilesAmppsphp-7.3ext»

If you are using XAMP

Goto XAMP Settings, Apache -> PHP.ini

Find, extension_dir = in php.ini, and set path of the php extension folder of your local machine. See the below example.

extension_dir = «C:phpext» (Check your path properly)

In my case, I had a similar issue after full installation of Debian 10.

Commandline:
php -v show I am using php7.4 but print phpinfo() gives me php7.3

Solution: Disable php7.3 Enable php7.4

   $ a2dismod php7.3
    
   $ a2enmod php7.4
    
   $ update-alternatives --set php /usr/bin/php7.4
   $ update-alternatives --set phar /usr/bin/phar7.4
   $ update-alternatives --set phar.phar /usr/bin/phar.phar7.4
   $ update-alternatives --set phpize /usr/bin/phpize7.4
   $ update-alternatives --set php-config /usr/bin/php-config7.4

Replace

include_path=C:Program Files (x86)xamppphpPEAR

with following

include_path="C:Program Files (x86)xamppphpPEAR"

i.e Add commas , i checked apache error logs it was showing syntax error so checked whole file for syntax errors.

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?

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.

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

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.

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.

at ubuntu 12.04 i had to change mssql.compatability_mode = On.
put On and works

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

a2dismod php5

and activated php7

a2enmod php7

Hope it may help anybody!

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

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.

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’

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)
