Session Array In PHP can store more items or data in a single variable but these are not available in different pages for use.
Any ordinary ( or normal ) array will loose its data as page execution ends. We have to transfer the array each time the visitor moves away from one page to other.
In some applications we need to retain the data as long as the visitor is active at site. Shopping cart is the best example for this. Visitor moves between different pages and adds items to the shopping cart.
We have to carry the shopping cart to all the pages along with the visitor. Visitor can add or remove items from the cart from any page.
Today, I will teach you how to create a session array in Hypertext Preprocessor (PHP). Session Array() variable has the ability to hold multiple data at once.
This will help you store various data that can be accessed in different pages.
Let’s begin:
First, you have to start the session to read all the session variable that are being declared.
[php]
session_start();
[/php]Second, declare a SESSION ARRAY variable to be able to store multiple data.
[php]
// It represent a container of data.
$_SESSION['cointainer'] = array();
[/php]Lastly is storing data in the session variable that you have declared.
[php]
$_SESSION['cointainer'][0]['Firstname']="Janobe";
$_SESSION['cointainer'][0]['Lastname']="Palacios";
$_SESSION['cointainer'][1]['Address']="Kabankalan City";
$_SESSION['cointainer'][1]['Email']="[email protected]";
// and you can also do this one.
$_SESSION['employee'] = array("Firstname"=>"Janobe", "Lastname"=>"Palacios", "Address"=>"Kabankalan", "Email"=>"[email protected]");
[/php]Output :
[php]
//It presents the value and their curresponding keys.
echo print_r($_SESSION['cointainer']) .'
;
echo print_r($_SESSION['employee']);
[/php]Frequently Asked Questions
How does this PHP project work?
Built with vanilla PHP (no framework) and MySQL backend. Standard structure: form HTML, PHP script handlers, MySQL via PDO or mysqli, sessions for auth, Bootstrap for responsive layout. Ready to extend for BSIT capstone scope.
What PHP and MySQL versions does this project require?
Most projects in this batch run on PHP 7.4 to PHP 8.2 with MySQL 5.7+ or MariaDB 10+. A few older projects need PHP 5.6 (deprecated, use XAMPP 7.x). To run: install XAMPP / WAMP / Laragon, extract project to htdocs, import the included .sql file via phpMyAdmin, edit the connection file (usually config.php or db_connect.php) with your DB credentials, browse to the project URL in your browser.
How do I set up the database for this PHP project?
Open phpMyAdmin (http://localhost/phpmyadmin/ on XAMPP), create a new empty database with the name specified in the project’s config.php. Click the Import tab, choose the included .sql file, click Go. Then edit config.php (or includes/connection.php) with: ‘localhost’, your MySQL username (usually ‘root’), your MySQL password (usually blank for XAMPP), and the database name.
Can I use this PHP project for a BSIT capstone or thesis?
Yes, but extend it. A bare CRUD app is too narrow for full capstone scope. Add: user roles via session checks, reports/dashboards (Chart.js + AJAX), PDF exports (TCPDF library), email notifications (PHPMailer), real domain extension (analytics, audit log, multi-branch support). Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘connection error’ or ‘undefined function mysqli_connect’?
Three common PHP issues: (1) Connection error: Apache + MySQL services not running in XAMPP control panel, OR database name in config.php does not match what you created in phpMyAdmin. (2) ‘undefined function mysqli_connect’: MySQL extension not enabled, in php.ini uncomment extension=mysqli (then restart Apache). (3) ‘No such file or directory’: MySQL socket path wrong, use 127.0.0.1 instead of localhost in the connection string.
