In this post I am describing the PHP Program which tell us about how to find prime number Series. Prime number are those number which are divisible by 1 and themselves. In this program we are using for loop, if condition and break statement.
<?php
if(isset($_POST['submit'])){
$number= $_POST['number'];
for($i=2;$i<=$number;$i++){ //loop for numerator
for($j=2;$j<=$number;$j++){ //loop for denominator
if($i<=$j){ //checking weather the value of denominator is greater then or equal to numerator
echo $i.","; //if this condition is true then the numerator is prime.
break;
}
if($i%$j==0){//this condition checks weather the numerator is divisible by denominator
break;
}
}
}
}
?>
