Prime

A PHP class for building an array of prime numbers that allows you to then check if a number is prime or to find an nth prime number

Getting started

Start by including the class prime.class.php, however you choose. In the example found in ./examples/1M-limit-with-details.php:

require_once 'path/to/prime.class.php'

Start by initializing the class and building the array, you can do that by either:

$prime = new \alexanderholman\prime();
$prime->buildPrimeNumbers();

Or you can autocomplete on __construct():

$prime = new \alexanderholman\prime( prime::BUILD_PRIME_NUMBERS );

From there you can call an nth prime number:

$prime->getNthPrimeNumber( $nth-term ) // where $nth-term in an integer
