Untuk memahami dengan mudah biasanya seorang
programmer akan cederung mempelajari dari basic terlebih dahulu. Yaitu dengan
memahami CRUD. CRUD adalah singkatan dari Create, Read, Update Dan Delete.
Crud berarti terdiri dari proses penginputan data ke database, menampilkan
data dari database, mengedit/mengupdate/mengubah data di database, dan juga
menghapus data pada database.
Membuat Database Baru
Kita buat database baru dengan nama
‘users’.

-- Dumping data for table `user`

INSERT INTO `user` (`id`, `nama`, `alamat`, `usia`)
VALUES

/*!40101 SET

/*!40101 SET

Membuat koneksi database.
<?php
class database{
var
$host="localhost";
var
$user="root";
var
$pass="";
var
$db="users";
function
__construct(){
mysql_connect($this->host,$this->user,$this->pass);
mysql_select_db($this->db);
}
function
tampil_data(){
$data=mysql_query("SELECT * FROM user");
while($d=mysql_fetch_array($data)){
$hasil[]=$d;
}
return $hasil;
}
function
input($nama,$alamat,$usia){
mysql_query("insert into user values('','$nama','$alamat','$usia')");
}
function
edit($id){
$data=mysql_query("SELECT
* FROM user WHERE id='$id'");
while($x=mysql_fetch_array($data)){
$result[]=$x;
}
return $result;
}
function
update($id,$nama,$alamat,$usia){
mysql_query("UPDATE user SET nama='$nama',alamat='$alamat',usia='$usia'
WHERE id='$id'");
}
function
hapus($id){
mysql_query("DELETE FROM user where id='$id'");
}
}
Menampilkan Data Dari Database.
<?php
error_reporting(0);
include'database.php';
$db= new database();
?>
<?php
$hal = $_GET['hal'];
if (empty($hal)){
?>

<?php

foreach ($db->tampil_data() as $x) {
?>

foreach($db->edit($_GET['id']) as $d){
?>

<td>

<?php
}
?>
</form>
<?php
}
?>
Membuat Aksi Tambah, Edit dan Hapus.
<?php
include 'database.php';
$db = new database();
$aksi = $_GET['aksi'];
if($aksi
== "tambah"){
$db->input($_POST['nama'],$_POST['alamat'],$_POST['usia']);
header("location:tampil.php");
}elseif($aksi
== "hapus"){
$db->hapus($_GET['id']);
header("location:tampil.php");
}elseif($aksi
== "update"){
$db->update($_POST['id'],$_POST['nama'],$_POST['alamat'],$_POST['usia']);
header("location:tampil.php");
}
?>
