There's a tag on SO: , which refers to the function print_r() in PHP. Currently , 43 out of 46 questions are also tagged (and one more tagged ).

According to the FAQ, a tag that cannot stand alone in a question should not exist, since this tag is dependant on the tag, it should be removed.

I say kill it! Kill it with fire!


  • Yes. And the echo tag to go with it (as long as it's paired with php) – Pekka Feb 17 '12 at 8:37

    Could you explain further why this tag is bad? – AakashM Feb 17 '12 at 9:36

    @AakashM - should there be a tag for every single PHP function? – Flexo Feb 17 '12 at 9:46

    @AakashM edited. But I think woodland already did the explaining. – Madara's Ghost Feb 17 '12 at 12:56

    But that's an argument for renaming it to, I don't know, php-print-r or similar, rather than deleting it. And @awoodland the choice isn't between 'none' and 'all'. If there are 40+ questions about this function then why shouldn't there be a tag? – AakashM Feb 17 '12 at 13:13

    @AakashM tags for specific parts of an API feels like a case of can't see the wood for the trees - i.e. getting caught in in the implementation details and missing the big picture – Flexo Feb 17 '12 at 13:22

    Hmm, ok, having done some research I see that print_r is actually just a somewhat uninteresting statement (I thought it might be something as exciting as, say, ls ). Objection withdrawn, although I think I'm still more tag-inclusionist than most people round here... – AakashM Feb 17 '12 at 13:36

Sigh. We don't need a tag for every single function in every single programming language. Most of the questions in are "why does it look like that" and "how do I parse the output." A few were about using it to assist in debugging.

As such, it's now gone. I cleaned up some horrible tagging along the way, like adding appropriate debugging tags.

While nuking, I discovered and , which has around 46 questions. I've nuked , as it only had 4 questions, but I've left alone when it wasn't paired with . It should also be nuked, but that'll be a different discussion. Most of the questions are probably going to be about debugging (or, worse, parsing output... sigh).
