# PHP Challenges: Compute the sum of the two reversed numbers and display the sum in reversed form

## PHP Challenges - 1: Exercise-17 with Solution

Write a PHP program to compute the sum of the two reversed numbers and display the sum in reversed form.

Input : 13, 14

Note : The result will not be unique for every number for example 31 is a reversed form of several numbers of 13, 130, 1300 etc. Therefore all the leading zeros will be omitted.

Explanation :

Sample Solution :

PHP Code :

``````<?php
function reverse_sum(\$n1, \$n2)
{
return reverse_integer(\$n1) + reverse_integer(\$n2);
}

function reverse_integer(\$n)
{
\$reverse = 0;
while (\$n > 0)
{
\$reverse = \$reverse * 10;
\$reverse = \$reverse + \$n % 10;
\$n = (int)(\$n/10);
}
return \$reverse;
}
print_r(reverse_sum(13, 14)."\n");
print_r(reverse_sum(130, 1)."\n");
print_r(reverse_sum(305, 794)."\n");
?>
```
```

Sample Output:

```72
32
1000
```
