Did you know that in the first version of php, each function name would be hashed to lookup the code to run it? And the hashing algorithm was: the first letter. So all the functions started with a different letter.
I hope this is not true
It's not. PHP used to use the function length as hash buckets, so by having evenly distributed lengths the execution time was faster. No idea where GP came up with that.
GP specifically talked about the first version of PHP, sounds like it was just a dummy implementation as they were working on PHP, that then later got replaced with a proper implementation :)
No it is, only 26 functions in total.
The Chinese had it way easier.
