How to declare an Array in PHP
How to declare an Array in PHP.
In this tutorial, you will learn how to use Arrays in PHP.
Array is a variable good for storing or holding one or more data at the same time. It can also be used in creating group of values where you will just declare a variable and add = array on it.
Here’s the code in declaring an array in PHP text file:
$arrayname = array();
To insert multiple values on your array variable, just simply follow this code:
$arrayname = array("itsourcecode","freetutorials","freesourcecode");
or just simply indexing the values manually:
$arrayname[0] = "itsourcecode"; $arrayname[1] = "freetutorials"; $arrayname[2] = "freesourcecode";
By inserting that line of code to your declared array, your array consists of that said values.
Usually, array values are being fetched by getting its array index.
Here are some notes that you should be considering in fetching the array data:
$arrayname[0];
and its results will be “itsourcecode” on your PHP file.

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.
