PHP 8.2 - Unsupported operand types: string * int

[Aruna KN]

if (!isset($inactiv)) $inactiv = 0;
else $inactiv = my_time()-$inactiv*2592000;

With PHP 8.2, code line 2 gives following error:

PHP Fatal error: Uncaught TypeError: Unsupported operand types: string * int

Please suggest me a solution

The error message suggests (because you have not provided all the information) that the variable $inactiv contains text data rather than an integral value.

Assuming $inactiv is an integer:

if (!isset($inactiv)) $inactiv = 0;
else $inactiv = my_time() - intval($inactiv) * 2592000;

It will be better if you make sure the $inactiv is always a number
