Function mysqli_get_client_info invoked with 0 parameters, 1 required.

Expected output

No errors.

The parameter has always been optional: https://www.php.net/manual/en/mysqli.get-client-info.php

Hi Juliette, these can be usually fixed in this file https://github.com/phpstan/phpstan-src/blob/master/resources/functionMap.php so feel free to send a PR :) Thanks

I looked at that file (even before reporting the issue) and couldn't for the life of me figure out how to indicate optional/required parameter, so sorry, no I will not fix this.

[ondrejmirtes]

There's documentation at the top of the file:

• A '=' following the <arg_name> indicates this arg is optional.

For example:

'explode' => ['array<int,string>|false', 'separator'=>'string', 'str'=>'string', 'limit='=>'int'],

Must have missed that. Still not going to send in a PR. I contribute to enough projects as it is.
