///////////////////////////////////////////////////////////////////////////////////// // // Class Prime Factors // It finds factors of whole numbers upto 100 Billion very fast and accurate // using a pre-existing data set. // (C) ABHISHEK SHUKLA // Date Created : Jan 13, 2016 // Last Modified: // Version 1.00 // This Software Should not be commercially used without prior and // explicit permission of the Author // ///////////////////////////////////////////////////////////////////////////////////// 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.
