Installation

composer require longitude-one/geo-parser

Usage

There are two use patterns for the parser. The value to be parsed can be passed into the constructor, then parse() called on the returned Parser object:

$input  = '79°56′55″W, 40°26′46″N';

$parser = new Parser($input);

$value = $parser->parse(); // [-79.948611111111, 40.446111111111]

If many values need to be parsed, a single Parser instance can be used:

$input1 = '56.242 E';
$input2 = '40:26:46 S';

$parser = new Parser();

$value1 = $parser->parse($input1); //56.242
$value2 = $parser->parse($input2); //-40.446111111111

  • 44:58:53.9 N
  1. Two of any one format separated by whitespace

  2. Two of any one format separated by a comma

Return

The parser will return an integer/float or an array containing a pair of these values.

Exceptions

The Lexer and Parser will throw exceptions implementing interface LongitudeOne\Geo\String\Exception\ExceptionInterface.
