README

The Postgres database supports ranges. This package provides capabilities to parse or build tstzranges for Postgres databases. This package attempts to fully support all the features of the tstzrange type. We made an exception for null values, which are interpreted as "infinity".

Installation

You can install the package via composer:

composer require inthere/datetime-range

Usage

$parser = new Parser(
    '["2015-08-14 16:07:28.956968+02","2018-08-14 16:07:28.956968+02"]',
     new DateTimeZone('UTC')
);
$dateTimeRange = $parser->parse();

This returns a DateTimeRange object, which can provide the lower and upper range:

$lowerRange = $dateTimeRange->getLowerRange();
$upperRange = $dateTimeRange->getUpperRange();

A Range object will be returned which contains the date, the boundary and which knows if the range is "infinity":

$lowerRange->isInfinity(); 
// returns a boolean

$lowerRange->getDateTime(); 
// returns a datetime object or null if infinity

$lowerRange->getBoundary(); 
// returns a boundary object

The Boundary object determines if the range is inclusive [] or exclusive () and if the range is lower or upper:

$boundary = $lowerRange->getBoundary();

$boundary->isLower(); 
// returns a boolean (true = lower, false = upper)

$boundary->isInclusive(); 
// returns a boolean (true = inclusive, false = exclusive)
