Hi,

An extra check is needed to avoid a fatal error in PHP 8 in relation to stripos() -- specifically the call in HttpHelper::transfer() which uses an offset of 12. If for whatever reason the haystack is less than 12 characters long, PHP 8 throws:

Uncaught ValueError: stripos(): Argument #3 ($offset) must be contained in argument #1 ($haystack) in /var/www/vendor/triagens/arangodb/lib/ArangoDBClient/HttpHelper.php on line 258

I've only seen this error once, after many requests on the same connection, and I'm not sure if there's another issue at play or whether a simple check of the string length is sufficient to resolve the issue?
