phpMyAdmin Error: The mbstring extension is missing. Please check your PHP configuration

I have a problem running phpMyAdmin. When I try to access phpMyAdmin in my browser, I get the error message: "The mbstring extension is missing. Please check your PHP configuration."

I have already searched on the internet for possible solutions. According to that, I made some modifications in php.ini file. I uncommented the line ";extension=php_mbstring.dll" and wrote the full path of the ext folder in extension_dir. Sadly, it still doesn't work.

Could you please help me finding the proper solution.

Did you restart your web server after the modification in php.ini? - Robert Gabriel
Is the DLL actually in the extension folder? - user1864610
Hey! The .dll is in the ext folder and I restarted apache after modifying php.ini. Btw, my OS is win 8. Everything looks OK, but it doesn't work. Is it possible that the versions of apache, php, mysql are not compatible? I installed: Apache 2.4.12 Win32, php-5.6.8-Win32-VC11-x86 and mysql-5.6.24-winx64. - Klemen Rejec
I solved the problem. I made a copy of php.ini and put it in c:\windows. It seems that the system did'n get the right information about the php.ini file. - Klemen Rejec
Please check the output of phpinfo() to see whether the extension appears to be loaded there. You can check that by loading your phpMyAdmin like https://example.com/phpmyadmin/phpinfo.php or by creating a new file (call it info.php or whatever) with the content <?php phpinfo(); ?> Use your web browser's search feature to look for "mbstring". - Isaac Bennetch

I've solved my problem by this way: Edit the php.ini file:

  1. change extension_dir = "ext" into extension_dir = "D:\php\ext" （please write ur own path）
  2. change ;extension=php_mbstring.dll into extension=php_mbstring.dll （delete the ";"）
  3. Then just save your php.ini file and copy it to ur Windows directory。(“C:\Windows“)
  4. restart the apache server。

The above is my solution,Hope it will work for u.

If you are ubuntu 14.04 and using php 5.6 You are missing out on mbstring and mysql module

Please install mbstring and mysql by

sudo apt-get install php5.6-mbstring
sudo apt-get install php5.6-mysql

and restart apache

sudo service apache2 restart

It could happen after you update your php version, for instance if you upgrade from php5.6 to php7.1 you need to run these commands:

sudo apt-get install php7.1-mbstring
sudo service apache2 restart

If your destination version is different you need to check if the mbstring package exsit or not, an example for php7.0:

sudo apt-cache search php7.0-mbstring

I found it useful to first check existence of all modules that you working with, then performing an upgrade, in addition to that update phpmyadmin after upgrading your php is a good idea

In my case i made a new installation of php7 using xampp, the error was in php.ini at line 699, i just did

include_path= C:\Program Files (x86)\xampp\php\PEAR

to

include_path= "C:\Program Files (x86)\xampp\php\PEAR"

and it worked for me.

I checked this by running the php.exe it gave me that error and i fixed it.

Change extension_dir = "ext" to extension_dir = "C:/php/ext" in php.ini.

You also need to define PHPIniDir - c:/php_install_path

It could raise the concern if you're either:

Case 1: Downgrading/ upgrading any PHP version.
Case 2: Enabling/Disabling (Switching) between PHP versions.

Here are some recommended commands I found helpful to fix these concerns:

Message 1: The mbstring extension is missing.......

sudo apt-get install php7.1-mbstring

Message 2: The mysqli extension is missing.......

sudo apt-get install php7.1-mysqli

Note: Tested with PHP version 7.1. Change PHP version as per requirement.
