Question

I’m new to PHP. A friend was helping me learn this, but he’s not available for a while. I know some things may simply not make sense (i’m learning, and I know this isn’t exactly a beginners function).

GOAL:
1. Find highest and lowest value within the array ($lemons).
2. Switch the placement of said values. (IE: 6, 2, 7, 8, 0, 9 –> 6, 2, 7, 8, 9, 0).

Thanks!

 <?php
 function switcheroo($lemons) {
    $min_lemons = min($lemons);
    $max_lemons = max($lemons);
    foreach ($lemons as $key => $value) {
        if ($max_lemons > 0) {
            $max_decoy = $min_lemons;
        }
        if ($min_lemons < 0) {
            $min_decoy = $max_lemons;
        }
    }
    return $lemons;
 }
 $lemons = array(6, 2, 7, 8, 0, 9);
 print_r(switcheroo($lemons));
 ?>

Answer 1

This is probably not the most elegant solution, but it works as intended:

$arr = array(6, 2, 7, 8, 0, 9);

echo 'Array before: <br /><pre>', print_r($arr, true);

function switcheroo($array) {
    $new_array = $array;

    $min_lemons = min($new_array);
    $max_lemons = max($new_array);

    $min_lemons_key = array_search($min_lemons, $new_array);
    $max_lemons_key = array_search($max_lemons, $new_array);

    $new_array[$min_lemons_key] = $max_lemons;
    $new_array[$max_lemons_key] = $min_lemons;

    return $new_array;
}

echo 'Array after: <br />', print_r(switcheroo($arr), true);
