PHP Exercises: Compute the sum of values in a given array of integers except the number 17
108. Sum of Array Except 17
Write a PHP program to compute the sum of values in a given array of integers except the number 17. Return 0 if the given array has no integer.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($nums)
{
// Initialize a variable $sum with a value of 0
$sum = 0;
// Iterate through the elements of the array using a for loop
for ($i = 0; $i < sizeof($nums); $i++)
{
// Check if the current element is not equal to 17, increment $sum by the value of the current element
if ($nums[$i] != 17) $sum += $nums[$i];
}
// Return the sum of values in the array except for the number 17
return $sum;
}
// Call the 'test' function with an array [1, 5, 7, 9, 10, 17] and print the result
echo "Sum of values in the array of integers except the number 17: ". test([1, 5, 7, 9, 10, 17] );
?>
Sample Output:
Sum of values in the array of integers except the number 17: 32
