php dotenv loaders benchmark

This is a very small script to show the execution time of 4 dotenv loaders for 10.000 executions each.

What is tested ?

Every loader has to reach the same point, so opening the .env file, parsing it and loading the result into $_ENV and $_SERVER.

Where does my results come from ?

I've got the execution time from the local execution (i5 1.8Ghz, php7.0.14).

But feel free to make yours:

composer install
./vendor/bin/phpbench run DotenvBench.php --report=default --revs=10000
