The document contains code for connecting to a MySQL database called "mahasiswa" located on the localhost server. It defines the host, username, password, and database, and establishes a connection using mysql_connect and mysql_select_db. There is also code that inserts received form data into a table in the database.

1. KONEKSI
<?php
$host = "localhost";
$username = "root";
$password = "";
$database = "mahasiswa";
$koneksi = mysql_connect($host, $username, $password);
$pilihdatabase = mysql_select_db($database, $koneksi);
// if ($pilihdatabase) echo"Berhasil";
// else echo "Gagal Koneksi";
?>

2. INPUT DATA KE DATABASE
<?php
include "koneksi.php“;
$nama_variabel = $_POST*‘nama_textfield'];
$query_insert = "insert into nama_tabel(field_tabel) values('$nama_textfield‘);";
$insert = mysql_query($query_insert);
if($insert)
{
include(“alamat_tujuan.php");
}
else
{
echo "Gagal , <a hreff=“index.html”></a>“;
}
?>

3. KONEKSI
<?php
$host = "localhost";
$username = "root";
$password = "";
$database = "mahasiswa";
$koneksi = mysql_connect($host, $username, $password);
$pilihdatabase = mysql_select_db($database, $koneksi);
// if ($pilihdatabase) echo"Berhasil";
// else echo "Gagal Koneksi";
?>

4. KONEKSI

$koneksi = mysql_connect($host, $username, $password);
$pilihdatabase = mysql_select_db($database, $koneksi);
// if ($pilihdatabase) echo"Berhasil";
// else echo "Gagal Koneksi";
?>
