I have a client who is running PHP 8.1 and it seems aspose/cells-sdk-php: v22.10 is not optimised for this as I get a lot of deprecated function warnings.
Looking at https://www.php.net/supported-versions.php, PHP 7.4 has EOL in one month: November 28, 2022, so the upgrade is about time.
Example of warning:
Deprecated function: Return type of Aspose\Cells\Cloud\Model\AccessTokenResponse::offsetExists($offset) should either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in include() (line 55 of /var/www/html/vendor/aspose/cells-sdk-php/lib/Model/AccessTokenResponse.php).
include(’/var/www/html/vendor/aspose/cells-sdk-php/lib/Model/AccessTokenResponse.php’) (Line: 571)
