Procedural:

test 1: 0.4619922161

test 2: 0.4763075113

test 3: 0.43635993

Object:

test 1: 0.4942417717

test 2: 0.4999971008

test 3: 0.498214469



Procedural wins 3 of 4 tests, object oriented wins 1 of 4 tests.



Post what you think about all this.

Description:
------------
mysqli_query()

is MUCH MUCH FASTER than

mysqli::query()



also MySQL PDO sucks as PDO is for dumb developers.





Test script:
---------------
