Lerdof On The Origins Of PHP's Function Names

20 December 2013

Rasmus Lerdof, PHP Mailing List:

Back when PHP had less than 100 functions and the function hashing mechanism was strlen(). In order to get a nice hash distribution of function names across the various function name lengths names were picked specifically to make them fit into a specific length bucket. This was circa late 1994 when PHP was a tool just for my own personal use and I wasn’t too worried about not being able to remember the few function names.

Some sense in the madness.
