SQLite CRUD Operation Using PHP Source Code

Submitted by razormist on Wednesday, March 4, 2020 - 11:50.

In this tutorial we will create a SQLite CRUD Operation using PHP. This code will manipulate a data with a several functionalities in the database server using SQLite query. The code use a SQLite query to (Create, Read, Update, Delete) to a certain data in a database server by applying a sets of parameter in the query. This a free program, you can apply this to your system as your own. We will be using SQLite that provides an interface for accessing the database. It includes class interfaces to the SQL commands. And also it allows you to create SQL functions and aggregate using PHP.

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 jquery that i used in this tutorial https://jquery.com/. Lastly, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/. Installing SQLite Browser We will now then install the SQLite data viewer, here's the link for the DB Browser for SQLite http://sqlitebrowser.org/.

Setting Up SQLite

First, we are going to enable SQLite 3 in our PHP.

Open localhost server folder XAMPP, etc and locate php.ini.
Open php.ini and enable sqlite3 by removing the semicolon in the line.
Save changes and Restart Server.

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=new SQLite3('db/db_member') or die("Unable to open database!");
	$query="CREATE TABLE IF NOT EXISTS `member`(mem_id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, firstname TEXT, lastname TEXT, address TEXT)";
 
	$conn->exec($query);
?>

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 you text editor, then save it as index.php.

	</div>

Creating the Main Function

This code contains the main function of the application. This code will will (Create, Read, Update, Delete) a data in the table with SQLite query. To do this just copy and write these block of codes as shown below inside the text editor, then save it as shown below. insert.php

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

delete.php

<?php
	require_once'conn.php';
 
	if(ISSET($_REQUEST['mem_id'])){
		$mem_id=$_REQUEST['mem_id'];
 
		$conn->query("DELETE FROM `member` WHERE `mem_id`='$mem_id'") or die("Failed to delete a row!");
		header('location:index.php');
	}
?>

update.php

<?php
	require_once'conn.php';
 
	if(ISSET($_POST['update'])){
		$mem_id=$_POST['mem_id'];
		$firstname=$_POST['firstname'];
		$lastname=$_POST['lastname'];
		$address=$_POST['address'];
 
 
		$query="UPDATE `member` SET `firstname`='$firstname', `lastname`='$lastname', `address`='$address' WHERE `mem_id`='$mem_id'";
 
		$conn->exec($query);
 
		header("location:index.php");
	}
?>

There you have it we successfully created a SQLite CRUD Operation using PHP. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!!!
