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

Install using composer

composer require levizwannah/php-nums-to-letters

Methods

toLetters($numbers)

Converts numbers to Letter format (Capital letters only);

use LeviZwannah\PhpNumsToLetters\Converter;

$letters = Converter::toLetters(12345);

toNumber($letters)

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

use LeviZwannah\PhpNumsToLetters\Converter;

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

isEqual($val1, $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

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

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

Decimal

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

Do the Math

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

Use cases

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