Hello Guys, This tutorial is all about How to Convert Number into Words in PHP. This tutorial is very easy and helpful as you will learn How to Convert Number into Words in PHP. So let’s get started:
First is to create a class name it “index.php” and put this code:
<!DOCTYPE>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Convert Number to Words</title>
</head>
<body>
<form method="post" action="">
<label>Enter Number
<input type="text" name="textfield" onchange="convert_number_to_words()" />
</label>
<input type="submit" value="Convert" />
</form>
<p>
Equivalent in words:
<?php
function convert_number_to_words($number) {
$hyphen = '-';
$conjunction = ' ';
$separator = ' ';
$negative = 'negative ';
$decimal = ' point ';
$dictionary = array(
0 => 'Zero',
1 => 'One',
2 => 'Two',
3 => 'Three',
4 => 'Four',
5 => 'Five',
6 => 'Six',
7 => 'Seven',
8 => 'Eight',
9 => 'Nine',
10 => 'Ten',
11 => 'Eleven',
12 => 'Twelve',
13 => 'Thirteen',
14 => 'Fourteen',
15 => 'Fifteen',
16 => 'Sixteen',
17 => 'Seventeen',
18 => 'Eighteen',
19 => 'Nineteen',
20 => 'Twenty',
30 => 'Thirty',
40 => 'Fourty',
50 => 'Fifty',
60 => 'Sixty',
70 => 'Seventy',

1000000000000000000 => 'Quintillion'
);
if (!is_numeric($number)) {
return false;
}
if (($number >= 0 && (int) $number < 0) || (int) $number < 0 - PHP_INT_MAX) {
// overflow
trigger_error(
'convert_number_to_words only accepts numbers between -' . PHP_INT_MAX . ' and ' . PHP_INT_MAX,
E_USER_WARNING
);
return false;
}
if ($number < 0) {
return $negative . convert_number_to_words(abs($number));
}
$string = $fraction = null;
if (strpos($number, '.') !== false) {
list($number, $fraction) = explode('.', $number);
}
switch (true) {
case $number < 21:
$string = $dictionary[$number];
break;
case $number < 100:
$tens = ((int) ($number / 10)) * 10;
$units = $number % 10;
$string = $dictionary[$tens];
if ($units) {
$string .= $hyphen . $dictionary[$units];
}
break;
case $number < 1000:
$hundreds = $number / 100;
$remainder = $number % 100;
$string = $dictionary[$hundreds] . ' ' . $dictionary[100];
if ($remainder) {
$string .= $conjunction . convert_number_to_words($remainder);
}
break;
default:
$baseUnit = pow(1000, floor(log($number, 1000)));
$numBaseUnits = (int) ($number / $baseUnit);
$remainder = $number % $baseUnit;
$string = convert_number_to_words($numBaseUnits) . ' ' . $dictionary[$baseUnit];
if ($remainder) {
$string .= $remainder < 100 ? $conjunction : $separator;
$string .= convert_number_to_words($remainder);
}
break;
}
if (null !== $fraction && is_numeric($fraction)) {
$string .= $decimal;
$words = array();
foreach (str_split((string) $fraction) as $number) {
$words[] = $dictionary[$number];
}
$string .= implode(' ', $words);
}
return $string;
}
echo '<b>'.convert_number_to_words($_POST['textfield']).'</b>';
?>
</p>
</body>

Simple as that. Go test the program!

Frequently Asked Questions
What does this PHP tutorial cover?
Focused PHP language or library tutorial showing a single concept with working code. Use as a building block when assembling a larger system.
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.
Where can I find more PHP projects with source code?
Browse the PHP Projects hub for the full library (300+ vanilla PHP systems). For modern PHP MVC alternatives see Laravel Projects (74 systems) or CodeIgniter Projects (32 systems). For BSIT-focused capstone idea lists see 150 Best Capstone Project Ideas.
How can the decimal be for example Ninety-one and not Nine One for 91
