Buat yang mau bikin program kecil-kecilan PHP ini nih aku punya code PHP mengubah(konversi) decimal to hexadecimal. semoga berhasil ya :)

<?php
if (isset($_POST['decimal'])){
    $des = $_POST['decimal'];
    $original = $_POST['decimal'];
    $hex = '';
    if (preg_match('/[^0-9]/',$des)) {
        die ("Maaf. Inputan Salah!");
    }
    else {
        while ($des > 0) {
            $hasil=$des%16; 
        switch($hasil){ 
        case 0: $hex.="0"; break;
        case 1: $hex.="1"; break;
        case 2: $hex.="2"; break;
        case 3: $hex.="3"; break;
        case 4: $hex.="4"; break;
        case 5: $hex.="5"; break;
        case 6: $hex.="6"; break;
        case 7: $hex.="7"; break;
        case 8: $hex.="8"; break;
        case 9: $hex.="9"; break;
        case 10: $hex.="A"; break;
        case 11: $hex.="B"; break;
        case 12: $hex.="C"; break;
        case 13: $hex.="D"; break;
        case 14: $hex.="E"; break;
        case 15: $hex.="F";
            default:break;
        }
        if($des/16 == 0){
        $sisa=($des%16);
        $des=$sisa;
    }
    else{
        $sisa=($des/16);
        $des=$sisa%16;
    }
        }
        
        $result = strrev($hex);
        echo "Bilangan $original (desimal) dalam hexa adalah $result.
        <a href='konversi_decimal_to_hexa.php'>Back</a> to the script";
    }
