PHP Numbers To Letter
=====================

[](#php-numbers-to-letter)

This Library converts Integers to Letters using A-Z. 0 = A, 25 = Z, using that, we can convert any integer to a letter format.

Installation
------------

[](#installation)

Install using composer

```
composer require levizwannah/php-nums-to-letters
```

Methods
-------

[](#methods)

### toLetters($numbers)

[](#tolettersnumbers)

Converts numbers to Letter format (Capital letters only);

```
use LeviZwannah\PhpNumsToLetters\Converter;

$letters = Converter::toLetters(12345);
```

### toNumber($letters)

[](#tonumberletters)

Converts letters to number format. The letters will be converted to uppercase first.

```
use LeviZwannah\PhpNumsToLetters\Converter;

$number = Converter::toNumber('AABC');
```

### isEqual($val1, $val2)

[](#isequalval1-val2)

This method tries to efficiently compares $val1 and $val2. Either of them can be string|integers. The comparison will still work.

```
use LeviZwannah\PhpNumsToLetters\Converter;

Converter::isEqual(1, 'B'); // true
Converter::isEqual(1, 1); // true;
Converter::isEqual('B', 'B'); // true;
Converter::isEqual(0, 'B'); // false
Converter::isEqual('dw', 'DW'); // true
```

Note
----

[](#note)

### Capital Letters only

[](#capital-letters-only)

Only Capital letters are used. Not lowercase so that we don't have any confusion. Imagine an Invoice number being AaBbC. That doesn't look good.

### Sign Numbers

[](#sign-numbers)

When the number has a negative sign, the sign will be preserved in the conversion. For example, -1 = -B and -C = -2.

### Decimal

[](#decimal)

Only Integers are supported at the moment because 1/26 gives a very long decimal.

Do the Math
-----------

[](#do-the-math)

With only 7 Letters, you can represent -8,031,810,176 to 8,031,810,176 numbers.

Use cases
---------

[](#use-cases)

1. Beautiful Order Invoice Numbers from Order IDS or some random Number.
2. Representing IDs
