PHP Fatal error when trying to access phpmyadmin mb_detect_encoding

A PHP Fatal error is a type of error that occurs when the PHP interpreter encounters a serious problem and is unable to continue executing the script. In this case, it appears to be related to a function called mb_detect_encoding, which is used to detect the character encoding of a string.

An example of a PHP Fatal error related to mb_detect_encoding might look like this:

Example of a PHP Fatal error related to mb_detect_encoding

Fatal error: Call to undefined function mb_detect_encoding() in /path/to/phpmyadmin/index.php on line 123

This error message indicates that the script is trying to call the mb_detect_encoding function on line 123 of the index.php file in the phpmyadmin directory, but the function is not defined. This is typically caused by a missing mbstring extension or incorrect configuration.

To resolve this error, follow these steps:

1. Open your php.ini configuration file and ensure the mbstring extension is enabled by uncommenting or adding:

   extension=mbstring

   Copy
2. Restart your web server or PHP-FPM service to apply the changes:

   sudo systemctl restart apache2
   # or
   sudo systemctl restart php-fpm

   Copy
3. Verify the extension is loaded by checking your phpinfo() output or running php -m in your terminal.
