[php] phpMyAdmin - The MySQL Extension is Missing

I installed everything separately (Apache, PHP, MySQL and phpMyAdmin) and do not use a compilation, everything works fine till now except phpMyAdmin.

The problem I am experiencing is, that the error message states that the "MySQL extension is missing", as soon as I try to call up:

localhost/phpmyadmin/index.php

And when I call up

localhost/phpmyadmin/setup/index.php

I have two messages where I do not know if it is supposed to be like that:

Bzip2 compression and decompression requires functions (bzopen, bzcompress) which are unavailable on this system.

and:

Zip decompression requires functions (zip_open) which are unavailable on this system.

Any suggestions?

In my case I had to install the extension:

yum install php php-mysql httpd

and then restart apache:

service httpd restart

That solved the problem.

Some linux distributions have a php_mysql and php_mysqli package to install.

Just check your php.ini file, In this file Semicolon(;) used for comment if you see then remove semicolon ;.

;extension=mysql.dll

Now your extension is enable but you need to restart appache

extension=mysql.dll

I had a similar issue, but it didn't help to add extension=mysql.so in my php.ini. It turned out that the mysql.so file was not in my extension folder nor anywhere else on my machine. Solved this by downloading the php source and building the extension manually and then copying it into the extension folder.

Just as others stated you need to remove the ';' from:
;extension=php_mysql.dll and
;extension=php_mysqli.dll

in your php.ini to enable mysql and mysqli extensions. But MOST IMPORTANT of all, you should set the extension_dir in your php.ini to point to your extensions directory. The default most of the time is "ext". You should change it to the absolute path to the extensions folder. i.e. if you have your xampp installed on drive C, then C:/xampp/php/ext is the absolute path to the ext folder, and It should work like a charm!

I just add

apt-get install php5-mysqlnd

This will ask to overwrite mysql.so from "php5-mysql".

This work for me.

Installing bzip2 and zip PHP extensions solved my issue in Ubuntu:

sudo apt-get install php7.0-bz2
sudo apt-get install php7.0-zip

Use php(you version)-(extension) to install and enable any missing modules that is required in the phpmyadmin readme.

You need to put the full path in the php ini when loading the mysql dll, i.e :-

extension=c:/php54/ext/php_mbstring.dll
extension=c:/php54/ext/php_mysql.dll

Then you don't need to move them to the windows folder.

Your installation is missing some php modules, there should be a list of required modules in the phpmyadmin readme. If you recently enabled the modules, try restarting the apache service / daemon.

Edit: As it seems, there is no single "enable these modules" in the docs, so enable either mysql or mysqli in your php.ini (you might need to install it first).

The two messages are not important if you do not intend to upload or download compressed file within phpMyAdmin. If you do, enable the zlib and / or bz2 modules.
