PHP function get checkboxes value - php

Question

I'm currently creating a website for a local sports union, so far I have created numerous pages, one of them being a table with the members and their information. Each member has a checkbox that contains the email address as a value. I should add that at the moment the members information is viewed in members.php, but the file that gets the information (The code you can see below) is from backend file fetch.php.
What I want is that when you check multiple checkboxes and press 'Send Mail', it should open a mailto:?bcc=mail1,mail2 etc.
if(mysqli_num_rows($result))
{
echo "<form method=\"post\">";
// Printing user information etc.
echo "<td><input name=\"email[]\" type=\"checkbox\" class=\"email-cb\" value=\"$email\"></td>";
echo "<tr><td><input type=\"submit\" value=\"Send Mail\"></td></tr>";
echo "</form>"
}
First of when you press the submit button (Or Send Mail if you like), it should simply do Send Mail
I have been working on this for a while and can't seem to find a solution, anyways I came up with this method to atleast extract emails (I think this is correct).
if(isset($_POST['email']) && is_array($_POST['email']))
{
foreach($_POST['email'] as $email)
{
$emailList = "mailto:?bcc=" . implode(',', $_POST['email']);
}
}

Answer 1

Change $_POST['fruit'] to $_POST['email'], and you don't need the loop, because the post data is already an array.:
if(isset($_POST['email']) && is_array($_POST['email']))
{
$emailList = "mailto:?bcc=" . implode(',', $_POST['email']);
}

What does $_POST['fruit']?? Maybe you are looking for this:
if(isset($_POST['email']) && is_array($_POST['email']))
{
foreach($_POST['email'] as $email)
{
$bccList .= $email.',';
}
$emailList = "mailto:?bcc=" . $bccList;
}
