Note

This package is the continuation of the now abandoned [creof/wkt-parser](https://github.com/creof/wkt-parser) package.

Installation
------------

[](#installation)

```
composer require longitude-one/wkt-parser
```

Usage
-----

[](#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 = 'POLYGON((0 0,10 0,10 10,0 10,0 0))';

$parser = new Parser($input);

$value = $parser->parse();
```

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

```
$input1 = 'POLYGON((0 0,10 0,10 10,0 10,0 0))';
$input2 = 'POINT(0,0)';

$parser = new Parser();

$value1 = $parser->parse($input1);
$value2 = $parser->parse($input2);
```

Return
------

[](#return)

The parser will return an array with the keys `type`, `value`, `srid`, and `dimension`.

- `type` string, the spatial object type (POINT, LINESTRING, etc.) without any dimension.
- `value` array, contains integer or float values for points, or nested arrays containing these based on spatial object type.
- `srid` integer, the SRID if EWKT value was parsed, `null` otherwise.
- `dimension` string, will contain `Z`, `M`, or `ZM` for the respective 3D and 4D objects, `null` otherwise.

Exceptions
----------

[](#exceptions)

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