Range converter

This simple class reduces arrays into compact strings by creating ranges when encountering neighboring integers. It can also expand strings with ranges back to the original array form.

Examples

Reducing ranges:

$converter = new Bradleyboy\Util\RangeConverter;
$converter->reduce([1,2,3,4,7,9,10,11]); // Returns: '1..4,7,9..11'

Expanding ranges:

$converter = new Bradleyboy\Util\RangeConverter;
$converter->expand('1..4,7,9..11'); // Returns: [1,2,3,4,7,9,10,11]

You can also set custom separators:

$converter = new Bradleyboy\Util\RangeConverter;
$converter->setSeparator('.')
          ->setRangeSeparator('-')
          ->reduce([1,2,3,4,7,9,10,11]); // Returns: '1-4.7.9-11'
