PHP's built in `base_convert` function supports bases ranging from 2 to 36. This library expands that range to 2 to 64.

Usage
=====

[](#usage)

Convert a number 100 from decimal to hexadecimal (from base 10 to base 16):

```
echo math\base_convert(100, 10, 16);
// echoes '64'
```

...and back:

```
echo math\base_convert(64, 16, 10);
// echoes '100'
```

Custom alphabets
----------------

[](#custom-alphabets)

Instead of integer bases, you can pass in the alphabet string to use for conversion (since integer bases are converted to alphabet strings anyways, i.e. hexadecimal alphabet is simply "0123456789abcdef").

Here we convert from base 10 to alphabet 'customizable'

```
echo math\base_convert(1234567890, 10, 'customizable');
// echoes 'slmmmmcui'
```

Here we convert from alphabet 'customizable' to alphabet 'isogram'

```
echo math\base_convert('slmmmmcui', 'customizable', 'isogram');
// echoes 'rorsirrioig'
```

And from alphabet 'isogram' back to base 10

```
echo math\base_convert('rorsirrioig', 'isogram', 10);
// echoes '1234567890'
```

So both `slmmmmcui` and `rorsirrioig`, but also `1234567890` describe the same value, but in different alphabets.

*NOTE:* All alphabets must be [isograms](https://en.wikipedia.org/wiki/Isogram)An isogram (also known as a "nonpattern word") is a logological term for a word or phrase without a repeating letter. Conveniently, the word `isogram` is an isogram as well.
