/*

|
|
This test fiel puts PHP's array to the test by running a million lookups on a handful of routes.
|
||
|
|
The routes are read from two files, blog.txt and github.txt, and added to two separate arrays.
|
||
|
|
The lookups are then run in two separate loops, one for each array.
|
||
|
|
Each lookup is timed and the memory usage is also printed out at regular intervals.
|
||
|
|
The requests are randomly picked from the array of routes.
