@jeffbyrnes do you mind addressing the md-links test that's failing? It seems to be unrelated to your change but it would be nice to fix.

@ramereth so here’s the thing: I tried to! But for some reason, those links always 503. If you visit the current ones in a browser, you’ll 301 → updated link, but even if I update the links to the result of the 301, md-links still says they're busted.

Maybe php.net has some kind of anti-robot setup that 503s non-human visitors?

@ramereth added ecdc59ff90d05c22a6a118e9da5c7c3444c02132 to fix the links in the docs, let's see how it acts this time.

Yeah, I wonder if they do. I'd vote to remove that specific check as I don't think we have it turned on globally. @sous-chefs/board thoughts? We mostly just need the MDL check.

[jeffbyrnes]

@ramereth well, other than md-links, things are looking green!

[ramereth]

@jeffbyrnes go ahead and remove that check in this PR so this will completely pass.

[jeffbyrnes]

Not sure why your commit didn’t show up @ramereth. I amended it slightly & force-pushed, it's here now.

[ramereth]

@jeffbyrnes yeah, GH being strange.. thanks
