DELETE DATA MYSQLI DI PHP
Pernyataan DELETE digunakan untuk rekaman rekaman dari tabel.
Ada 2 cara penulisan syntax MySQLi di PHP yaitu:
1. MySQLi berorientasi objek
2. MySQLi prosedural
1. DELETE DATA MYSQLI BERORIENTASI OBJEK DI PHP
Contoh delete data "Mahasiswa" di PHP sebagai berikut:
<!DOCTYPE html>
<html>
<body>
<?php
// Data
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydb";
// Membuat koneksi
$conn = new mysqli($servername, $username, $password, $dbname);
// Check koneksi
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully<br>";
// Menghapus data
$sql = "DELETE FROM Mahasiswa WHERE id=2";
if ($conn->query($sql) === TRUE) {
echo "Delete Mahasiswa successfully";
} else {
echo "Error deleting data: " . $conn->error;
}
$conn->close();
?>
</body>
2. DELETE DATA MYSQLI PROSEDURAL DI PHP
Contoh delete data "Mahasiswa" di PHP sebagai berikut:
<!DOCTYPE html>
<html>
<body>
<?php
// Data
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydb";
// Membuat koneksi
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check koneksi
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully<br>";
// Menghapus data
$sql = "DELETE FROM Mahasiswa WHERE id=2";
if (mysqli_query($conn, $sql)) {
echo "Delete Mahasiswa successfully";
} else {
echo "Error deleting data: " . mysqli_error($conn);
}
mysqli_close($conn);
?>
</body>
