Phil Bennett has returned to a topic he covered earlier to refresh some of the statistics and add a few newer technologies to the mix. In this new post he benchmarks some of the more popular PHP-based dependency injection containers.

A few months ago I wrote a post detailing and benchmarking several dependency injection containers. Recently there have been some changes to some of these containers and some new packages have appeared in the community so I decided to revisit the post and update it a little. When I say a little, I'm going to be re-writing the entire post to give you a little more information about the containers and some more in-depth benchmarks.

Several new DI containers were added including the AuraDi, PHP-DI and LeagueDi. His benchmarks measure the time taken for these operations:

• Extremely nested object fetching
• Registering all objects
• Resolving objects (w/dependencies) using a factory
• Injecting pre-defined constructor values
• Resolving dependencies with setter calls

Code for the test and graphs of the outcomes are provided for each benchmark on the list. There's also a bit of analysis at the end of the post detailing some of the pros and cons of each.
