If you need this information before submitting the form, you'd like to use Javascript instead of PHP.

According to another Stackoverflow thread, there is a way to get these files using Javascript/jQuery:

Example using jQuery:

var files = $(".upload").first().files;
var filesCount = files.length;

alert(filesCount);

However, you say you'll need this as an PHP variable. I don't really understand, since you'll need this information before the form submit.

Well, you can use AJAX for PHP to process the information if that's a solution for you:

http://api.jquery.com/jquery.post/

Example:

var files = $(".upload").first().files;
var filesCount = files.length;

$.ajax({
  type: "POST",
  url: 'URL_TO_PHP_SCRIPT',
  data: {
      count: filesCount
  }
});
