128. Replace 5 with 0 and Shift Zeros to Right

Write a PHP program to create a new array after replacing all the values 5 with 0 shifting all zeros to right direction.

Sample Solution:

PHP Code :

<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
{ 	
    // Get the size of the input array
    $size = sizeof($numbers);

    // Initialize variables: $index to keep track of the position in the new array, and $arra1 as an array filled with zeros
    $index = 0;
    $arra1 = array_fill(0, $size, 0);

    // Iterate through the elements of the input array using a for loop
    for ($i = 0; $i < $size; $i++)
    {
        // Check if the current element is not equal to '5'
        if ($numbers[$i] != 5)
        {
            // Assign the current element to the next position in the new array and increment $index
            $arra1[$index] = $numbers[$i];
            $index++;
        }
    }

    // Return the new array with '5' removed
    return $arra1;
}   

// Call the 'test' function with an example array and store the result in the variable 'result'
$result = test([1, 2, 5, 3, 5, 7, 5, 9, 11] );

// Print the result array as a string
echo "New array: " . implode(',', $result);
?>

Sample Output:

New array: 1,2,3,7,9,11,0,0,0
