older version of PHP

[satis4action]

if the PHP version is older than 8.0, you need to add this line to the beginning of the php script ;-) Otherwise export to csv doesnot working

if (!function_exists('str_starts_with')) { function str_starts_with(string $haystack, string $needle): bool { return substr($haystack, 0, strlen($needle)) === $needle; } }

Or use https://github.com/symfony/polyfill-php80 and it will polyfill all the methods for PHP 8
