phpMyAdmin - The MySQL Extension is Missing

Question

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?

Answer 1

At first make sure you have mysql installed properly. You can ensure it just by checking that whether you can access mysql using mysql command promp. So if you mysql is working then probably it is not loading. For that follow the steps given below

First of all, you must find your php.ini. It could be anywhere but if you create a small php file with the

<?php phpinfo(); ?>

script it will tell you where it is. Just look at the path of loaded configuration file. Common places include /etc/apache/, /etc/php4/apache2/php.ini, /etc/php5/apache2/php.ini or even /usr/local/lib/php.ini for Windows it may be C:\Users\username\PHP\php.ini

Edit your server’s php.ini and look for the following line. Remove the ‘;’ from the start of the line and restart Apache. Things should work fine now!

;extension=mysql.so

should become

extension=mysql.so

For windows it will be

;extension=mysql.dll

should become

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.
