delete all data in table using php

In this tutorial, we will create a Simple Delete All Data In Table using PHP. This code can delete your entire data when the user clicks the delete button. The system uses the MySQLi DELETE query to cancel your full table content without providing an id in the WHERE clause. This a user-friendly program. Feel free to modify and use it for your system.

We will be using PHP as a scripting language and interpreter that is used primarily on any web server, including xamp, wamp, etc. It is being applied to many popular websites because of the modern approach as its today.

Getting Started:

First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the 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_all; after that, click Import, then locate the database file inside the folder of the application then click ok.

mysql delete all rows

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
    $conn = mysqli_connect('localhost', 'root', '', 'db_all') or die(mysqli_error());
    if(!$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.

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 save_ member.php.

<?php
    require_once 'conn.php';
 
    $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 delete all 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 delete_members.php

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