In this tutorial we will create a Emptying Table In MySQLi using PHP. This code can empty your table when the user click the empty button button.The code use MySQLi TRUNCATE TABLE query to empty your existing table instantly in the MySQLi database. This a user-friendly program feel free to modify and use it to your system. We will be using PHP as a scripting language and interpreter that is used primarily on any webserver including xamp, wamp, etc. It is being use to any famous websites because of modern approach as its today.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html. And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating Database

Open your database web server then create a database name in it db_empty_table, after that click Import then locate the database file inside the folder of the application then click ok. tut1

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
	$conn=mysqli_connect("localhost", "root", "", "db_empty_table");
 
	if(!$conn){
		die("Error: Failed to connect to database!");
	}
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="UTF-8" name="viewport" content="width=device-width, intial-scale=1"/>
		<link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
	</head>	
<body>
	<nav class="navabr navbar-default">
		<div class="container-fluid">
			<a class="navbar-brand" href="https://sourcecodeter.com">Sourceodester</a>
		</div>
	</nav>
	<div class="col-md-3"></div>
	<div class="col-md-6 well">
		<h3 class="text-primary">PHP - Emptying Table In MySQLi</h3>
		<hr style="border-top:1px dotted #ccc;"/>
		<div class="col-md-4">
			<form method="POST" action="insert.php">
				<div class="form-group">
					<label>Firstname</label>
					<input type="text" name="firstname" class="form-control" required="required"/>
				</div>
				<div class="form-group">
					<label>Lastbane</label>
					<input type="text" name="lastname" class="form-control" required="required"/>
				</div>
				<div class="form-group">
					<label>Address</label>
					<input type="text" name="address" class="form-control" required="required"/>
				</div>
				<center><button class="btn btn-primary" name="insert">Insert</button></center>
			</form>
		</div>
		<div class="col-md-8">
			<a class="btn btn-danger" href="empty.php">Empty Table</a>
			<br /><br />
			<table class="table table-bordered">
				<thead class="alert-info">
					<tr>
						<th>Firstname</th>
						<th>Lastname</th>
						<th>Address</th>
					</tr>
				</thead>
				<tbody>
					<?php
						require'conn.php';
 
						$query=mysqli_query($conn, "SELECT * FROM `member`") or die(mysqli_error());
						while($fetch=mysqli_fetch_array($query)){
							echo"<tr>
									<td>".$fetch['firstname']."</td>
									<td>".$fetch['lastname']."</td>
									<td>".$fetch['address']."</td>
								</tr>";
						}
					?>
				</tbody>
			</table>
		</div>
	</div>
</body>
</html>

Creating PHP Query

This code contains the php query of the application. This code will store the data inputs to the database server. To do that just copy and write this block of codes inside the text editor, then save it as insert.php.

<?php
	require_once'conn.php';
 
	if(ISSET($_POST['insert'])){
		$firstname=$_POST['firstname'];
		$lastname=$_POST['lastname'];
		$address=$_POST['address'];
 
		mysqli_query($conn, "INSERT INTO `member` VALUES('', '$firstname', '$lastname', '$address')") or die(mysqli_error());
 
		header("location: index.php");
	}
?>

Creating the Main Function

This code contains the main function of the application. This code will empty your table data when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as empty.php

<?php
	require_once'conn.php';
 
	mysqli_query($conn, "TRUNCATE TABLE `member`") or die(mysqli_error());
 
	header("location: index.php");
?>
