can not install "pux" by using composer.

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for corneltek/pux dev-master -> satisfiable by corneltek/pux[dev-master].
- corneltek/pux dev-master requires phpsgi/phpsgi dev-master -> no matching package found.

Add "phpsgi/phpsgi": "@dev", to your composer.json

I have write one Router class, to resolve the URL to callback handler.
I have test it and get the belong result (my router is fast in this benchmark, i will test it with the C extension):

R3 extension is not loaded. Skipping initialization for "Worst-case matching" test using R3.
R3 extension is not loaded. Skipping initialization for "First route matching" test using R3.

Worst-case matching

This benchmark matches the last route and unknown route. It generates a randomly prefixed and suffixed route in an attempt to thwart any optimization. 1,000 routes each with 9 arguments.

This benchmark consists of 12 tests. Each test is executed 1,000 times, the results pruned, and then averaged. Values that fall outside of 3 standard deviations of the mean are discarded.

First route matching

This benchmark tests how quickly each router can match the first route. 1,000 routes each with 9 arguments.

This benchmark consists of 7 tests. Each test is executed 1,000 times, the results pruned, and then averaged. Values that fall outside of 3 standard deviations of the mean are discarded.
