Get values between min and max in PHP object

I am trying to get the values between min and max in a PHP object.
This is the output of the PHP object:

var_dump($suggestions->productionYear);

Outputs:

object(stdClass)#6567 (2) { ["min"]=> int(2016) ["max"]=> int(2019) }

But I want to output all the values between the min and max like this: 2016 , 2017, 2018 and 2019

Does someone know how I get the output like above? I know I have to use a foreach loop but everytime I get output NULL

<?php foreach ($suggestions->productionYear as $productionYear) { ?>
    <option value="<?php echo $productionYear; ?>"
    ><?php echo $productionYear; ?></option>
<?php } ?>

Thanks for your time!

Neither min nor max have any special meaning in PHP objects as you seem to assume. If you want your object to be iterable with foreach you need to make it implement the Iterator interface. You can find a full implementation at Example #1 Basic usage.

Otherwise, just build your own loop or generate a range:

$suggestions = (object)null;
$suggestions->productionYear = (object)['min' => 2016, 'max' => 2019];

for ($productionYear = $suggestions->productionYear->min; $productionYear <= $suggestions->productionYear->max; $productionYear++) { ?>
    <option value="<?php echo $productionYear; ?>"><?php echo $productionYear; ?></option>
<?php }

foreach (range($suggestions->productionYear->min, $suggestions->productionYear->max) as $productionYear) { ?>
    <option value="<?php echo $productionYear; ?>"><?php echo $productionYear; ?></option>
<?php }

You can use range() with foreach(), See: https://www.php.net/manual/en/function.range.php

foreach (range($min, $max) as $year) {
   // other code goes here
}

For your case something like,

$min = $suggestions->productionYear->min;
$max = $suggestions->productionYear->max;

<?php foreach (range($min,$max) as $year) { ?>
    <option value="<?php echo $year; ?>"
    ><?php echo $year; ?></option>
<?php } ?>

As you can see on var_dump, it outputs an object. So you first need to convert that into an array and then loop over it.

(array) $suggestions->productionYear;
