PHP Pass Checkbox values and dropdown values to Next Page POST - php

Question

Iam trying a solution in PHP/MYSQL where in there is a some country list with a checkbox. Certain countries have something called entities which is a drop down which shows Micro, Small, Large as a dropdown. This entity dropdown appears for certain countries only. I am able to pass the checkbox checked values to next page. But i need to pass the value of the entity selected in the drop down also. Iam not able to acheieve that. My code ie posted below. Here i need to pass the value of the drop down (select - entity_selected) also to next page:
<?php
echo '<table border="1">';
while($row1 = mysqli_fetch_array($result_country)) {
$country1 = $row1["country"];
$entity1 = $row1["entity"];
echo '<tr>';
?>
<td><input name="check_list[]" type="checkbox" value="<?php echo $country1;?>"> <?php echo $country1;?></td>
<td>
<?php
if($entity1 == 'Yes'){ ?>
<select class="form-control selectpicker" name="entity_selected">
<option value="Micro">Micro</option>
<option value="Small">Small</option>
<option value="Large">Large</option>
</select>
<?php }
?>
</td>
<?php echo '</tr>'; } ?>
</table>
The Next page code is below to get the check box selected countries.
if(!empty($_POST['check_list'])) {
foreach($_POST['check_list'] as $check) {
echo $check;
}
}
How can i get the drop down values here? iam getting the checkbox (countries values correctly). Can anyone pls help me on this pls?

<form method="POST" action="nextpage.php">
<table border="1">
<?php
$i = 0;
while($row1 = mysqli_fetch_array($result_country)) {
$country1 = $row1['country'];
$entity1 = $row1['entity'];
echo "<tr>";
?>
<td>
<input name="check_list<?=$i ?>" type="checkbox" value="<?php echo $country1;?>"> <?php echo $country1;?>

<td>
<?php
if($entity1=="Yes") {

<select class="form-control selectpicker" name="entity_selected<?=$i ?>">

<option value="Large">Large</option>
</select>
<?php
};

</td>
<?php
$i++;
echo "</tr>";

</form>
nextpage.php:
<?php
$entities = $checklist = [];
foreach($_POST as $k => $v) {
if(preg_match("/^checklist(\d+)$/", $k, $matches))
$checklist[intval($matches[0])] = $v;
unset($matches);
if(preg_match("/^entity_selected(\d+)$/", $k, $matches))
