PHP - ask user input for dates and pass to script - php

Question

I have a php script here to create login at our datacenter for myself, but this script is doing the login for next week if i run it after 12:00 on monday, and a lot of times I'm not there the whole week, so I want to improve this script by asking for user input and pass the dates that I will be there so the script only picks up on those dates. I know i have to do this with stdin and I do have a part that works, but i have no idea on how to integrate this into the current script and how to make sure i can give multiple dates
My stdin part that does ask my for a date, but no idea on how to combine it:
<?php
function promptDateFromUser(string $prompt, string $dateFormat): DateTimeInterface
{
echo "{$prompt} [$dateFormat]: ";
$stdin = fopen('php://stdin', 'r');
$line = trim(fgets(STDIN));
fclose($stdin);
$dateTime = DateTimeImmutable::createFromFormat('Y-m-d', $line);
if (! $dateTime instanceof DateTimeInterface) {
throw new UnexpectedValueException('Invalid datetime format');
}
}
$dateTime = promptDateFromUser("Please insert date:", 'Y-m-d');
?>
My login script as of now:
<?php
require 'shared.php';
restore_exception_handler();
restore_error_handler();
$md = new RevisionModificationData;
$md->comment = 'Set by the dcgaccess script';
$date = new DateTime();
$hour = (int)$date->format('H');
$dow = (int)$date->format('w');
if (($dow === 1 && $hour > 12) || ($dow > 1 && $dow < 6)) {
$add = 'P' . (8 - $dow) . 'D';
$date->add(new DateInterval($add));
}
if (($dow === 1 && $hour <= 12) || $dow === 0 || $dow === 6) {
if ($dow === 6) {
$date->add(new DateInterval('P2D'));
} elseif ($dow === 0 ) {
$date->add(new DateInterval('P1D'));
}
}
$tomorrow = $date->format('Y-m-d');
$duration = 720;
$customerId = 30;
$purpose = 'DCG visit';
$phoneNumber = '';
$name = 'SOME NAME, REMOVED FOR PUBLICATION';
$colo = Colo::getByName($name);
Ensure::notNull($colo, "Colo for RackSpace is null when it should not be!");
$spaces = $colo->getRackSpaces();
foreach ($spaces as $space) {
$rackSpace = $space;
}
Ensure::notNull($rackSpace, "RackSpace is null when it should not be!");
if ($colo->getCustomerId() != $customerId) {
throw new UserException(ErrorCodes::PERMISSION_DENIED);
}
for ($x = 0; $x < 5; $x++) {
$start = $tomorrow." 8:00:00";
$end = Util::stringToMysqlDateTime($start . ' + ' . $duration . ' minutes');
$shouldSms = strlen((string)$phoneNumber) > 0;
$req = BioAccessRequest::create($rackSpace, $purpose, $start, $end, $shouldSms, $md);
$users = BioAccessUser::getAll();
foreach ($users as $user) {
if ($user->name === 'USER NAME') {
$req->addBioAccessUser($user, $md);
}
}
$req->request();
echo "Access requested for: ", $tomorrow, PHP_EOL;
$date->add(new DateInterval('P1D'));
$tomorrow = $date->format('Y-m-d');
}
?>
I'm a big php noob, so some explanation is greatly appreciated!

after some help from a friend, i managed to solve this:
#!/usr/bin/env php
