Prime Number Program in PHP



Prime Number :- 

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. For example, 3 is a prime number because it has no positive divisors other than 1 and 3.

Prime numbers are below:-

2, 3, 5, 7, 11, 13, 17, 19 ....

Here I am writing the PHP program to check whether a number is Prime or not.

<?php
function CheckPrime($number){
    for($x=2;$x<$number;$x++){
        if($number%$x == 0){
            return 0;
        }
    }
    return 1;
}

$a = CheckPrime(17);
if ($a==0)
    echo 'This is not a Prime Number.....'."\n";
else
    echo 'This is a Prime Number..'."\n";
?>

Output :- This is a Prime Number..

Using the above program you can check whether a number is prime or not in PHP.
