Answer 1

You can do this using sprintf() Function in PHP as shown below:

<?php

function invoiceNumber(){
    return sprintf('%02d-%04d', mt_rand(10, 99), mt_rand(1000, 9999));
}

function contractNumber(){
    $integerPart = mt_rand(100, 999);
    $decimalPart = mt_rand(0, 999999) / 1000000;
    $contractNumber = sprintf('%03d.%06f', $integerPart, $decimalPart);
    return $contractNumber;
}

$request['no_vak'] = invoiceNumber();
$request['no_contract'] = contractNumber();

?>

You can use FakerPHP for this.

$faker = \Faker\Factory::create();
$rand1 = $faker->regexify('[0-9]{2}-[0-9]{4}');
$rand2 = $faker->regexify('[0-9]{3}\.[0-9]{5}');

Please note that you'll probably need to move FakerPHP from require-dev to require in your composer.json if you want to run this code in production.
