Description
___________
 
This error appears when PHP cannot retrieve the character set used by the connection to MySQL. The mysqli_get_charset() function tries to fetch the data from the connexion, but the result was not usable.

Such error is probably circumstancial: the server may have gone away, or crashed, leading to no answer about charset.

Example
_______

.. code-block:: php

   <?php
   
       $db = mysqli_init();
       $db->real_connect(localhost,user,password,test);
       var_dump($db->get_charset()); 
   
   ?>

Solutions
_________

+ Check the server health.
