These scripts compare three different styles of programming:

1. fast.php is quick to both implement and execute, but difficult to read, understand and maintain.
2. readable.php is easy to read, understand and maintain, but slower to execute and to implement.
3. both.php is easy to read, understand and maintain. It is fast to execute, but slow to implement.

File	Technical debt	Implementation time	Execution time
fast.php	3 units	~1 hour	0.5s
readable.php	1-2 units	~2 hours	10s
both.php	1 unit	~3 hours	0.5s

All three have the same output. Test data is not currently provided.
