On my HTML page I can add hidden fields by pressing a button (JavaScript).
The names of the newly added hidden fields are
hidden_field_001
hidden_field_002
hidden_field_003
hidden_field_...

By clicking another button (JavaScript) I can remove some hidden fields
again.

If I'm finished then I press the submit button (method="post").
With the PHP script I try to read the hidden fields:

for ($i = 0; $i <= 9; $i++) {
$array[$i] = $_POST['hidden_field_00' . $i];
}

However, my problem is how to figure out within PHP if the hidden field
still exists or if I've deleted it before.
