A PHP Method to Generates Fibonacci (Golden Number) list using Division

In this code snippet, we’ll show an example PHP Method to Generates Fibonacci (Golden Number) list using Division.

A PHP Method to Generates Fibonacci (Golden Number) list using Division

<?php
/**
 * Generates a list of division results based on a given Fibonacci list.
 *
 * This function takes an array representing a Fibonacci sequence as input and returns
 * an associative array containing the division results of consecutive Fibonacci numbers.
 * The input Fibonacci list is first reversed, and then each division is calculated and
 * stored in the output array with informative keys.
 *
 * @param array $fibo_list The Fibonacci list to process. This array should contain at least two elements.
 * @return array The list of division results as an associative array. The array keys represent
 * the division statements, and the values represent the division results.
 * 
 * 
 * @example
 * $fibo_list = array(0, 1, 1, 2, 3, 5, 8);
 * $results = goldenNumber($fibo_list);
 * // The $results array may look like:
 * // array(
 * //    "the division of 8 by 5 is" => 1.6,
 * //    "the division of 3 by 2 is" => 1.5,
 * //    "the division of 1 by 1 is" => 1,
 * // )
 */
function goldenNumber(array $fibo_list)
{
    $reversed_list = array_reverse($fibo_list);
    $list = array();
    for ($i = 0; $i < count($reversed_list); $i++) {
        if (($reversed_list[$i] != 0) && (($reversed_list[$i] != 1) || ($reversed_list[$i + 1] != 0))) {
            $key = "the division of $reversed_list[$i] by " . $reversed_list[$i + 1] . " is";
            $list[$key] = $reversed_list[$i] / $reversed_list[$i + 1];

        }

    }
    return $list;
}

$fibo_list = array(0, 1, 1, 2, 3, 5, 8);
var_dump(goldenNumber($fibo_list));
