Usage

MathPackage Class

calcDivisors function

Takes an integer and returns an array with all of the integer's divisors (except for 1 and the number itself). Prime numbers are not allowed.

• param int
• returns array with divisors

calcFactorial function

Calculates and returns the factorial for a given input. Input below 0 and above 12 is not allowed.

• param int
• returns int

calcPrimeNumbers function

Takes an array with integers finds the prime numbers and returns the result as a XML document which each found prime number in a ‘number’ node

• param 1 array with integers
• param 2 bool $saveXML, true for saving XML file, false for display XML
• returns result as XML document

isPrimeNumber function

Check if a number is prime

• param int
• returns bool

filterPrimes function

Takes the prime numbers from an array of integers

• param array on integers
• returns array with primes

$arrayNums = [2,3,4,5,6,7,11,12,13,17,19,23,29,30,31,37,40,41,43,47,53,59,60,61,67,71,73,74,79,83,89,97,101,102,'asd'];

print_r("<br><br>Divisors of $num: ");
print_r(MathPackage::calcDivisors( $num ));

print_r("<br><br>Factorial of $factorial: ");
print_r(MathPackage::calcFactorial( $factorial ));

print_r("<br><br>The prime numbers from [".implode(",", $arrayNums)."]<br>");
print_r(MathPackage::calcPrimeNumbers( $arrayNums, $saveXML = false ));

if($saveXML){
    print_r("Result in primeNumbers.xml file.");
}
