Improved base\_convert for PHP
==============================

[](#improved-base_convert-for-php)

PHP's `base_convert` function does not handle large numbers well. This library does, and can also optionally zero-pad to a minimum column width.

It is a drop-in replacement for base\_convert, supporting base 2 through 36, and has additional features for padding and case.

The gmp and bcmath extensions are optionally used for improved performance.

Additional documentation about the library can be found on [MediaWiki.org](https://www.mediawiki.org/wiki/base_convert).

Usage
-----

[](#usage)

```
// Using padding, outputs 01010
\Wikimedia\base_convert( 'a', '36', '2', '5' )
```

Running tests
-------------

[](#running-tests)

```
composer install --prefer-dist
composer test

```

History
-------

[](#history)

This library was first introduced in [MediaWiki 1.7](https://www.mediawiki.org/wiki/MediaWiki_1.7) ([r14777](https://www.mediawiki.org/wiki/Special:Code/MediaWiki/14777)), and overhauled in [MediaWiki 1.21](https://www.mediawiki.org/wiki/MediaWiki_1.21) ([9b9daadc46](https://gerrit.wikimedia.org/r/40552)). It was split out of the MediaWiki codebase and published as an independent library during the [MediaWiki 1.27](https://www.mediawiki.org/wiki/MediaWiki_1.27) development cycle.
