PHP Exercises: Mutate the original array to filter out the values specified

PHP: Exercise-88 with Solution

Write a PHP program to mutate the original array to filter out the values specified.

Sample Solution:

PHP Code:

<?php
// Licence: https://bit.ly/2CFA5XY

// Function definition for 'pull' that takes an array reference and variable number of parameters as input
function pull(&$items, ...$params)
{
    // Use 'array_diff' to remove elements specified by the parameters from the array
    // Use 'array_values' to reindex the array after removal
    $items = array_values(array_diff($items, $params));

    // Return the modified array
    return $items;
}

// Initialize an array '$items' with repeated values
$items = ['a', 'b', 'c', 'a', 'b', 'c'];

// Call 'pull' with the array and specified values to be removed, then display the result using 'print_r'
print_r(pull($items, 'a', 'c'));

?>

Sample Output:

Array
(
    [0] => b
    [1] => b
)
