Write a PHP programme to sum 1 to 10 numbers using while loop PHP

Write a PHP program to sum 1 to 10 numbers using while loop PHP:

Here this the program 

//Program:

<?php

$sum = 0; 

$n = 10;

$i=1;

 while($i<=$n)

 {

    $sum += $i;

    $i++;

 }

echo $sum;
?>

In this program, we take three variables named $sum,$n, and $i. $sum variable store the sum of numbers and $n viable used to store that number to sum and same $i use as a counter that counts the number and at the start, you can initialize the value which you want to start the addition of number.

for example:
if we want to sum 1 to 10 then we initialise the value as,
$i=0;
$n=10;

when $i got equal to $n then while loop will exit and print the sum of 1 to 10.

$sum += $i;
Read this: know about += operator

if you need any help then you can mention in the comment section.
