Description:
------------
The (extremely useful) php.net/$keyword redirect currently doesn't support the array of pre-defined constants available within PHP. This is an extra problem because the manual search typically doesn't return relevant results for many of them: as an example, try <http://php.net/PHP_EOL> -- the right place to go would be <http://php.net/reserved.constants>, but that's not in the list.

I've concocted a patch for error.php to add support for the "core predefined constants" and the magic constants (including __NAMESPACE__, since it looks like we'll be getting that one soon enough), and it's at <http://www.adamharvey.name/stuff/error-constants.diff>. Hard-coding the constants into the manual page moves array probably isn't the best approach, but there's going to need to be an evil-looking list somewhere, I guess.

This patch doesn't address the longer list of "standard predefined constants", but it's a start. If the approach is acceptable (or a better one is recommended), I'll look at cooking up a patch for those as well.

I love the idea, but I really don't want _all_ the constants listed in the error handler - and needing to update the error handler on every new constant...

I however can't come up with better way..

Couldn't PhD perhaps generate a file with core/standard constants for each time the manual is pushed to the mirrors?

Coming back to this one, perhaps we look into using a database an sqlite database for lookups (I'm pretty sure we have such for indexing), and then a handler to determine where to redirect to based on a lookup so we never have to add new constants. It does also seem more efficient than my initial idea of extending the hack by letting PhD generate a list for php-web.
