Dalam dunia pengembangan web, PHP merupakan salah satu bahasa pemrograman yang paling banyak digunakan, terutama dalam hal pengelolaan database. Untuk memudahkan proses tersebut, PHP menyediakan ekstensi Data Objects (PDO) yang menyajikan antarmuka konsisten untuk berinteraksi dengan berbagai jenis database. Artikel ini bertujuan untuk memberikan contoh Operasi PHP CRUD menggunakan Ekstensi PDO.

Buat Database dengan nama tbluser

SQL
SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";

--
-- Table structure for table `tblusers`
--

CREATE TABLE IF NOT EXISTS `tblusers` (
  `id` int(11) NOT NULL,
  `FirstName` varchar(150) NOT NULL,
  `LastName` varchar(150) NOT NULL,
  `EmailId` varchar(120) NOT NULL,
  `ContactNumber` char(11) NOT NULL,
  `Address` varchar(255) NOT NULL,
  `PostingDate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=latin1;

--
-- Dumping data for table `tblusers`
--

INSERT INTO `tblusers` (`id`, `FirstName`, `LastName`, `EmailId`, `ContactNumber`, `Address`, `PostingDate`) VALUES
(1, 'Iwan', 'nuh', 'joo@gmail.com', '7855788888', 'makassar', '2017-12-12 06:27:53');

--
-- Indexes for dumped tables
--

--
-- Indexes for table `tblusers`
--
ALTER TABLE `tblusers`
  ADD PRIMARY KEY (`id`);

--
-- AUTO_INCREMENT for dumped tables
--

--
-- AUTO_INCREMENT for table `tblusers`
--
ALTER TABLE `tblusers`
  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT,AUTO_INCREMENT=7;
SQL

Buat file dengan nama index.php Pada file ini kita menggunakan Framework Bootstrap sebagai template.

PHP
<?php
// include database connection file
require_once'dbconfig.php';

// Code for record deletion
if(isset($_REQUEST['del']))
{
//Get row id
$uid=intval($_GET['del']);
//Qyery for deletion
$sql = "delete from tblusers WHERE  id=:id";
// Prepare query for execution
$query = $dbh->prepare($sql);
// bind the parameters
$query-> bindParam(':id',$uid, PDO::PARAM_STR);
// Query Execution
$query -> execute();
// Mesage after updation
echo "<script>alert('Record Updated successfully');</script>";
// Code for redirection
echo "<script>window.location.href='index.php'</script>"; 
}

PHP

Buat file dengan nama dbconfig.php. File ini berfungsi sebagai koneksi ke databse.

PHP
<?php 
// DB credentials.
define('DB_HOST','localhost');
define('DB_USER','');
define('DB_PASS','');
define('DB_NAME','');
// Establish database connection.
try
{
$dbh = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME,DB_USER, DB_PASS);
}
catch (PDOException $e)
{
exit("Error: " . $e->getMessage());
}
?>
PHP

Sesuaikan DB_USER, DP_PASS dan DB_NAME sesuai dengan database pada hosting kalian.

Buat file dengan nama insert.php file ini berisi sebagai form input dan perintah untuk memasukkan data kedatabase

PHP
<?php
// include database connection file
require_once'dbconfig.php';
if(isset($_POST['insert']))
{

// Posted Values  
$fname=$_POST['firstname'];
$lname=$_POST['lastname'];
$emailid=$_POST['emailid'];
$contactno=$_POST['contactno'];
$address=$_POST['address'];

// Query for Insertion
$sql="INSERT INTO tblusers(FirstName,LastName,EmailId,ContactNumber,Address) VALUES(:fn,:ln,:eml,:cno,:adrss)";
//Prepare Query for Execution
$query = $dbh->prepare($sql);
// Bind the parameters
$query->bindParam(':fn',$fname,PDO::PARAM_STR);
$query->bindParam(':ln',$lname,PDO::PARAM_STR);
$query->bindParam(':eml',$emailid,PDO::PARAM_STR);
$query->bindParam(':cno',$contactno,PDO::PARAM_STR);
$query->bindParam(':adrss',$address,PDO::PARAM_STR);
// Query Execution
$query->execute();
// Check that the insertion really worked. If the last inserted id is greater than zero, the insertion worked.
$lastInsertId = $dbh->lastInsertId();
if($lastInsertId)
{
// Message for successfull insertion
echo "<script>alert('Record inserted successfully');</script>";
echo "<script>window.location.href='index.php'</script>"; 
}
else 
{
// Message for unsuccessfull insertion
echo "<script>alert('Something went wrong. Please try again');</script>";
echo "<script>window.location.href='index.php'</script>"; 
}
}
