Let’s get started.
CodeIgniter 4 Installation
To create a CodeIgniter 4 setup run this given command into your shell or terminal. Please make sure composer should be installed.
$ composer create-project codeigniter4/appstarter codeigniter-4
Assuming you have successfully installed application into your local system.
Environment (.env) Setup
When we install CodeIgniter 4, we will have env file at root. To use the environment variables means using variables at global scope we need to do env to .env
Either we can do via renaming file as simple as that. Also we can do by terminal command.
Open project in terminal
$ cp env .env
Above command will create a copy of env file to .env file. Now we are ready to use environment variables.
Enable Development Mode
CodeIgniter starts up in production mode by default. You need to make it in development mode to see any error if you are working with application.
Open .env file from root.
# CI_ENVIRONMENT = production
// Do it to
CI_ENVIRONMENT = development
Now application is in development mode.
Method #1: Number To Words within Controller
Let’s consider a application controller. In this controller we will create a method which handles number to words conversion.
Open project into terminal and create this controller:
$ php spark make:controller DemoController
It will create a controller file DemoController.php inside /app/Controllers folder.
Open DemoController.php file and write this code into it.
<?php namespace App\Controllers; use App\Controllers\BaseController; class DemoController extends BaseController { public function index() { $word = $this->numberToWord(120); print($word); echo "<br>"; $word = $this->numberToWord(4500); print($word); echo "<br>"; $word = $this->numberToWord(58010); print($word); } public function numberToWord($num = '') { $num = (string) ((int) $num); if ((int) ($num) && ctype_digit($num)) { $words = array(); $num = str_replace(array(',', ' '), '', trim($num)); $list1 = array( '', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen' ); $list2 = array( '', 'ten', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety', 'hundred' ); $list3 = array( '', 'thousand', 'million', 'billion', 'trillion', 'quadrillion', 'quintillion', 'sextillion', 'septillion', 'octillion', 'nonillion', 'decillion', 'undecillion', 'duodecillion', 'tredecillion', 'quattuordecillion', 'quindecillion', 'sexdecillion', 'septendecillion', 'octodecillion', 'novemdecillion', 'vigintillion' ); $num_length = strlen($num); $levels = (int) (($num_length + 2) / 3); $max_length = $levels * 3; $num = substr('00' . $num, -$max_length); $num_levels = str_split($num, 3); foreach ($num_levels as $num_part) { $levels--; $hundreds = (int) ($num_part / 100); $hundreds = ($hundreds ? ' ' . $list1[$hundreds] . ' Hundred' . ($hundreds == 1 ? '' : 's') . ' ' : ''); $tens = (int) ($num_part % 100); $singles = ''; if ($tens < 20) { $tens = ($tens ? ' ' . $list1[$tens] . ' ' : ''); } else { $tens = (int) ($tens / 10); $tens = ' ' . $list2[$tens] . ' '; $singles = (int) ($num_part % 10); $singles = ' ' . $list1[$singles] . ' '; } $words[] = $hundreds . $tens . $singles . (($levels && (int) ($num_part)) ? ' ' . $list3[$levels] . ' ' : ''); } $commas = count($words); if ($commas > 1) { $commas = $commas - 1; } $words = implode(', ', $words); $words = trim(str_replace(' ,', ',', ucwords($words)), ', '); if ($commas) { $words = str_replace(',', ' and', $words); } return $words; } else if (!((int) $num)) { return 'Zero'; } return ''; } }
Add Route
Open Routes.php file from /Config folder and add this route into it.
//... $routes->get("number-to-words", "DemoController::index"); //...
Once we will call the route, output will be:
One Hundred Twenty
Four Thousand and Five Hundreds
Fifty Eight Thousand and Ten
Method #2: Number To Words (Custom Helper)
Here,
We will create a custom CodeIgniter helper i.e numberToWord() via which we will register the concept of number to words conversion.
We need to register custom helper in CodeIgniter 4 –
- Create a file number_helper.php inside /app/Helpers folder.
Open number_helper.php from application and write this code into it.
<?php if (!function_exists("numberToWord")) { // Number to words function numberToWord($num = '') { $num = (string) ((int) $num); if ((int) ($num) && ctype_digit($num)) { $words = array(); $num = str_replace(array(',', ' '), '', trim($num)); $list1 = array( '', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen' ); $list2 = array( '', 'ten', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety', 'hundred' ); $list3 = array( '', 'thousand', 'million', 'billion', 'trillion', 'quadrillion', 'quintillion', 'sextillion', 'septillion', 'octillion', 'nonillion', 'decillion', 'undecillion', 'duodecillion', 'tredecillion', 'quattuordecillion', 'quindecillion', 'sexdecillion', 'septendecillion', 'octodecillion', 'novemdecillion', 'vigintillion' ); $num_length = strlen($num); $levels = (int) (($num_length + 2) / 3); $max_length = $levels * 3; $num = substr('00' . $num, -$max_length); $num_levels = str_split($num, 3); foreach ($num_levels as $num_part) { $levels--; $hundreds = (int) ($num_part / 100); $hundreds = ($hundreds ? ' ' . $list1[$hundreds] . ' Hundred' . ($hundreds == 1 ? '' : 's') . ' ' : ''); $tens = (int) ($num_part % 100); $singles = ''; if ($tens < 20) { $tens = ($tens ? ' ' . $list1[$tens] . ' ' : ''); } else { $tens = (int) ($tens / 10); $tens = ' ' . $list2[$tens] . ' '; $singles = (int) ($num_part % 10); $singles = ' ' . $list1[$singles] . ' '; } $words[] = $hundreds . $tens . $singles . (($levels && (int) ($num_part)) ? ' ' . $list3[$levels] . ' ' : ''); } $commas = count($words); if ($commas > 1) { $commas = $commas - 1; } $words = implode(', ', $words); $words = trim(str_replace(' ,', ',', ucwords($words)), ', '); if ($commas) { $words = str_replace(',', ' and', $words); } return $words; } else if (!((int) $num)) { return 'Zero'; } return ''; } }
Usage of Helper
Open DemoController.php and write this code into it.
<?php namespace App\Controllers; use App\Controllers\BaseController; class DemoController extends BaseController { public function __construct() { helper("number"); // Load helper } public function index() { $word = numberToWord(120); print($word); echo "<br>"; $word = numberToWord(4500); print($word); echo "<br>"; $word = numberToWord(58010); print($word); } }
Output
One Hundred Twenty
Four Thousand and Five Hundreds
Fifty Eight Thousand and Ten
