Change your HTML and give a name attribute to all your checkboxes, like so:

 4. What language (s) are you currently using? 

Multi select:

 English

French

Spanish

Brazilian Portuguese

Italian

German

Japanese

Once the form has been submitted, the name attributes will be passed as array and they'll be accessible using the same variable. Now, you can use isset() to check if a particular item was set:

if(isset($_POST['checkbox'])) {
  print_r($_POST); //print all checked elements
}

If you want to get the number of checkboxes that were checked, you can use count():

$number = count($_POST['checkbox']);

Note: currently, only the first element has a value attribute. You'll have to add it for the rest of the checkboxes for it to work properly.

Hope this helps!
