Note

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

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

[](#installation)

```
composer require longitude-one/wkb-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:

```
$parser = new Parser($input);

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

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

```
$parser = new Parser();

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

### Input value

[](#input-value)

#### Encoding

[](#encoding)

The parser currently supports 3 WKB encodings:

- OGC v1.1
- OGC v1.2
- PostGIS EWKB

#### Format

[](#format)

The parser supports a number of input formats:

- Binary string (as returned from database or `pack('H*', $hexString)`)
- Bare hexadecimal text string (`'01010000003D0AD7A3.....'`)
- Hexadecimal test string prepended with `x`, `X`, `0x`, or `0X` (`'0x01010000003D0AD7A3.....'`, etc.)

Return
------

[](#return)

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

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

Exceptions
----------

[](#exceptions)

The `Reader` and `Parser` will throw exceptions implementing interface `CrEOF\Geo\WKB\Exception\ExceptionInterface`.
