Hi! 

Need some help with a piece of code. New to this, so it is quite a pain in the ass!

I need to make a code that shows the what spare change you should give back. 

so for example. when i put in 7 it should give back: 

1 x 5 euro

1 x euro 

Which it does. but i have some trouble putting in the 1 euro's. for example when i put in 21 it gives back 

2 x 10 euro 

Who can help me out?

<?php

function results($value)

{

    if ($value >= 10) {

        echo floor($value / 10) . ' X 10 euro ' . PHP_EOL;

        $modulf = $value % 10;

        if ($modulf >= 5) {

            echo floor($modulf / 5) . ' X 5 euro ' . PHP_EOL;

            $modult = $modulf % 5;

            if ($modult >= 2) {

                echo floor($modult / 2) . ' X 2 euro ' . PHP_EOL;

            }

        }

    } else if ($value >= 5) {

        echo floor($value / 5) . ' X 5 euro ' . PHP_EOL;

        $modult = $value % 5;

        if ($modult >= 2) {

            echo floor($modult / 2) . ' X 2 euro ' . PHP_EOL;

        }

    } else if ($value >= 2) {

        echo floor($value / 2) . ' X 2 euro ' . PHP_EOL;

    } else if ($value >= 1) {

        echo floor($value / 1) . ' X 1 euro ' . PHP_EOL;

    }

}

if (count($argv) > 1) {

    $input = $argv[1];

    if (!(is_numeric($input))) {

        echo 'Geen wisselgeld' . PHP_EOL;

    } else {

        $input = intval($argv[1]);

        if ($input !== 0) {

            results($input);

        } else {

            echo 'Geld wisselgeld' . PHP_EOL;

        }

    }

} else {

    echo 'Geen wisselgeld' . PHP_EOL;

}

Try

$amount = 28;

$change = calcChange($amount);

foreach ($change as $v => $n) {
    echo "$n &euro;$v coins <br>";
}

function calcChange($amt)
{
    $coins = [ 10 => 0, 5 => 0, 2 => 0, 1 => 0 ];
    
    foreach ($coins as $v => &$n) {
        $n = intdiv($amt, $v);
        $amt -= $n * $v;
    }
    return $coins;
}
