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
