CRUD merupakan singakatan dari Created, Read, Update dan Delete. Biasanya kalau kita membuat aplikasi didalam Pemprograman Web dalam hal ini adalah PHP kita sudah terbiasa dengan MYSQL perkembangan bahasa pemprograman PHP dewasa ini mengalami perubahan yang signifikan sehingga kita tidak dapat terus menerus menggunakan sintak MYSQL di PHP. MYSQLI extension merupakan pengembangan dari versi sebelumnya. Contoh CRUD PHP ini penulis kembangkan dari contoh yang penulis dapatkan di internet. Program sebelumnya masih menggunakan MYSQL namun penulis kembangkan berbasis MYSQLI
CREATE TABLE IF NOT EXISTS `mhsasia` (
`id` int(5) NOT NULL auto_increment,
`nama` varchar(35) NOT NULL,
`alamat` varchar(35) NOT NULL,
`nim` varchar(12) NOT NULL,
`email` varchar(34) NOT NULL,
`no_telpon` varchar(34) NOT NULL,
`photo` varchar(200) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=987 ;
Selanjutnya di folder htdocs pada directory penyimpanan aplikasi CRUD MYSQLI tambahkan satu folder dan beri nama photo. contohnya sebagai berikut :
1. koneksi.php
<?php
ob_start(); //ditambahkan untuk mengabaikan pengiriman header, berlaku juga untuk mengabaikan pesan error header
$host="localhost";
$user="root";
$pass="";
$db="latihan_db_2";
$koneksi=mysqli_connect($host,$user,$pass,$db);
?>
2. index.php
