In this tutorial, we will create a Sort Data In SQLite3 using PHP. This code will sort data in the table when the user clicks a button on the table. The system uses the PHP POST method to launch a specific function that sorts data in the SQLite database using a SELECT query and adding a parameter ORDER BY that set as either ASC or DESC. 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.
Table of Contents
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/.
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.
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.

Creating the SQLite Query
This code contains the SQLite query of the application. This code will store the data inputs to SQLite database. To do this just copy and write these block of codes as shown below 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']; $query="INSERT INTO `member` (firstname, lastname, address) VALUES('$firstname', '$lastname', '$address')"; $conn->exec($query); header("location:index.php"); } ?>
Creating the Main Function
This code contains the main function of the application. This code will sort data in the SQLite database. To do this just copy and write these block of codes as shown below inside the text editor, then save it as sort.php.
<?php require'conn.php'; if(ISSET($_POST['asc'])){ $query=$conn->query("SELECT * FROM `member` ORDER BY `lastname` ASC") or die("Failed to fetch row!"); while($fetch=$query->fetchArray()){ echo"<tr><td>".$fetch['firstname']."</td><td>".$fetch['lastname']."</td><td>".$fetch['address']."</td></tr>"; } }else if(ISSET($_POST['desc'])){ $query=$conn->query("SELECT * FROM `member` ORDER BY `lastname` DESC") or die("Failed to fetch row!"); while($fetch=$query->fetchArray()){ echo"<tr><td>".$fetch['firstname']."</td><td>".$fetch['lastname']."</td><td>".$fetch['address']."</td></tr>"; } }else{ $query=$conn->query("SELECT * FROM `member`") or die("Failed to fetch row!"); while($fetch=$query->fetchArray()){ echo"<tr><td>".$fetch['firstname']."</td><td>".$fetch['lastname']."</td><td>".$fetch['address']."</td></tr>"; } } ?>
