Taming SplPriorityQueue

SplPriorityQueue is a fantastic new feature of PHP 5.3. However, in trying to utilize it in a few projects recently, I've run into some behavior that's (a) non-intuitive, and (b) in some cases at least, undesired. In this post, I'll present my solutions.

Applying FilterIterator to Directory Iteration

I'm currently doing research and prototyping for autoloading alternatives in Zend Framework 2.0. One approach I'm looking at involves creating explicit class/file maps; these tend to be much faster than using the include_path, but do require some additional setup.

My algorithm for generating the maps was absurdly simple:

  • Scan the filesystem for PHP files
  • If the file does not contain an interface, class, or abstract class, skip it.
  • If it does, get its declared namespace and classname

The question was what implementation approach to use.

I'm well aware of RecursiveDirectoryIterator, and planned to use that. However, I also had heard of FilterIterator, and wondered if I could tie that in somehow. In the end, I could, but the solution was non-obvious.

Search tips

  • Use #{some tag} or tag:{some tag} to filter by tag; using this more than once will find results that match all tags.
  • Use year:{year} to filter by year. If you use this multiple times, the last one wins.
  • Use begin:{year-month-day} to restrict to results beginning on that day. Last one wins.
  • Use end:{year-month-day} to restrict to results ending on that day. Last one wins.
