Usage is very simple
1) Include class script file
include("primefactors.php");
2) Initiate a new object of class prime_factors
$test=new prime_factors;
3) Call factorize function passing the desired whole number in braces
$test->factorize(13);
The output is 'Finding factors of 13... 13';
$test->factorize(1024);
The output is 'Finding factors of 1024... 2,2,2,2,2,2,2,2,2';
4) By default class echoes the result, but setting $test->echo=0; will mute the echoes.
5) $factors=$test->factorize(N); syntax returns array of all prime factors of N.
If N itself is prime array containing only one factor N is returned.
6) This class comes with a pre-existing data set used for speedy alogorithm which should
be kept intact for integrity of results. Any changes in that data-set may result in
wiered or falsified results.
