Get all elements from associative array and send them via POST method in PHP

I'm developing a simple contact form. I have an associative array $_POST['hid']. Something like this:

Array["0" => "Location0", "1" => "Location1", "2" => "Location2"]

I'm trying to send this array as an email with a view on client side as:

Locations:

I'm using this PHP code but it returns me only the last element from the array in the email...

for ($i = 0; $i < count($_POST['hid']); $i++) {
    $a=$_POST['hid'][$i];
}

$email_content .= "Locations:\n$a\n";

Also I tried to send $_POST['hid'] but it returns me Array in the email.

So the question is how can I send all array values via POST method and receive them in the email. Not just first or last element. Thank you for your help.

You need to use something like this:

$a = 'Locations:<ul>';
for ($i = 0; $i < count($_POST['hid']); $i++) {
    $a .= '<li>' . $_POST['hid'][$i] . '</li>';
}
$a .= '</ul>';
$email_content = $a;

Just add a dot (.) before $a

$a = 'Locations:<ul>';
for ($i = 0; $i < count($_POST['hid']); $i++) {
    $a .= '<li>' . $_POST['hid'][$i] . '</li>';
}
$a .= '</ul>';
$email_content = $a;

for ($i = 0; $i < count($_POST['hid']); $i++) {
     $a=$_POST['hid'][$i];
     $email_content .= "Locations:\n$a\n";
}

you change the variable $a all the time, that's why you have always the same value.

you can do it by a shorter way also like:

for ($i = 0; $i < count($_POST['hid']); $i++) {
     $email_content .= "Locations:\n".$_POST['hid'][$i]."\n";
}

or more clean (to me) like:

foreach($_POST['hid'] as $location) {
     $email_content .= "Locations:\n$location\n";
}

EDIT: but the result isn't the one expected so more like this:

$email_content .= "Locations:\n";
$locations = "";
foreach($_POST['hid'] as $location) {
    $locations .="$location\n";
}
$email_content .= $locations;

$hid = $_POST['hid'];
for ($i = 0; $i < count($hid); $i++) {
   $a=$hid[$i];
   $email_content .= "Locations:\n$a\n";
}

Or you can use foreach, goes like this:

$hid = $_POST['hid'];
foreach ($hid as $h){
   $a=$h[$i];
   $email_content .= "Locations:\n$a\n";
}

I'd probably do this instead:

$array = []
array_map(function($item) use (&$array){
 $array[] = $item;
},$_POST['hid']);

$array should contain all your values
