@PaolaRuby Very helpful comment, thank you for your contribution.

@frank9999 I'm not sure what the problem is. I've marked the Session tests skipped for now. I haven't looked into it yet, but I don't know why PHP is concerned about setting INI values when in the CLI...there's no CGI, no concept of HTTP, I don't know why PHP think headers are being sent.

Would love some help with this.
