Convert numbers between arbitrary notations

mindplay/nbase

This script provides a converter between numbers encoded with n-base notation., _(*1)

, _(*2)

Usage

Any notation (using ASCII characters) can be used., _(*3)

For example, to convert from decimal to hexadecimal notation:, _(*4)

$converter = new NBaseConverter();

echo $converter->convert('12345', 'dec', 'hex'); // => '3039'

You can define your custom notations via the public $notations property - the notation names supplied to the convert method must be defined in $notation., _(*5)

Common notations such as bin, hex, dec and oct are pre-defined, as well as base62 and base64, plus a URL-safe variation of base64 called url64 which uses - and _ instead of the standard + and / used by base64., _(*6)

Also, a useful notation legible is available, which excludes visually ambiguous characters such as 1 and l, 0 and O, which can be used to shorten numeric IDs, e.g. for use in URLs., _(*7)

Refer to the source code for a list of pre-defined notations., _(*8)
