Your question is confused, but if I understand correctly, you want to have access to information from all users who have filled in this information. If so, you need a database to store this data and be able to query it later.
An example with Mysql would be:
$server = "localhost";
$user = "root";
$password = "";
$dbname = "nomeDoBanco";
//Criar a conexao
$con = mysqli_connect($server, $user, $password, $dbname);
After that, you need a query to register:
mysqli_query($con,"INSERT INTO nomeTabela (campos) VALUES $info1, $info2..." ):
And to display all to the administrator:
mysqli_query($con,"SELECT * FROM nomeTabela");
If that’s not what you want, explain your question better. If you have no idea what I’m talking about, do a little research on Database.
Obs. for page targeting you can use:
echo "<script> location.href='../páginaQualquer.php'; </script>";
Put this code snippet in the question, it’s easier to understand
