A PHP Error occured

[GrandM1961]

In php 8.2 i get this error:

A PHP Error was encountered

Severity: 8192

Message: Creation of dynamic property CI_DB_mysqli_driver::$failover is deprecated

Filename: database/DB_driver.php

Line Number: 371

Backtrace:

File: /Users/hans/Sites/CMS/application/config/config.php
Line: 536
Function: DB

File: /Users/hans/Sites/CMS/index.php
Line: 327
Function: require_once

I have checked the file in question and it says this:

public function __construct($params)
{
if (is_array($params))
{
foreach ($params as $key => $val)
{
$this->$key = $val;
}
}

	log_message('info', 'Database Driver Class Initialized');
}

$this->$key=>$val is where the php gives the error, any way how to resolve this??

Use php v7.4 at maximum or less than it...but not high then it, because this script only support php v7.4 at maximum...
