Display Data From Database Table Using PDO in PHP with Source Code
In this tutorial, we will create a Display Data From Database Table using PDO. This code will display PDO data from the database table when the user clicks the button. The system uses a PDO SELECT query to read all the available data in the database then display it as a readable content using fetch(). This is a user-friendly kind of program, feel free to modify it.
We will be using PDO as a query scripting it an acronym for PHP Data Objects. It is a lean, clean, and consistent way to access databases. This means developers can write portable code much more accessible.
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_pdo_table, after that, click Import then locates the database file inside the folder of the application then click ok.
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
$conn = new PDO( 'mysql:host=localhost;dbname=db_pdo_table', 'root', '');
if(!$conn){
die("Fatal Error: Connection Failed!");
}
?>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.

This code contains the main function of the application. This code will display data from the database when the button is clicked. To do this just kindly write these block of codes inside the text editor, then save it as pdo_table.php.
<?php
require_once 'conn.php';
if(ISSET($_POST['display'])){
$sql = "SELECT * FROM `user`";
$query = $conn->prepare($sql);
$query->execute();
while($fetch = $query->fetch()){
?>
<tr>
<td><?php echo $fetch['firstname']?></td>
<td><?php echo $fetch['lastname']?></td>
<td><?php echo $fetch['address']?></td>
</tr>
<?php
}
}
?>
