README

Latest Version on Packagist

The gasparesganga/php-shapefile package is extremely handy for working directly with Shapefiles, but we work mostly in Laravel and prefer the collection-style APIs found throughout. This package simply wraps the original ShapefileReader class in a LazyCollection to make iterating on it a bit more familiar.

Installation

You can install the package via composer:

composer require teamzac/laravel-shapefiles

Usage

$reader = new TeamZac\LaravelShapefiles\Reader('file_or_directory_path_here');

$reader->count(); // total number of records
$reader->each(function($geometry) {
    // do something
});

You can pass a reference to the .shp file, or the directory containing the .shp file, when instantiating the Reader.

When iterating in the original package, you'd receive an instance of Shapefile\Geometry\Geometry. We also wrap this in a class that adds a couple of additional methods:

...
$reader->each(function($geometry) {
    $geometry->asGeoJson(); // passes through to the getGeoJSON() method with the "as" verbiage commonly used in Laravel
    $geometry->asJson(); // a convenience method that runs the GeoJSON through json_decode first
    $geometry->getData('ID'); // allows retreival of a specific key in the data array
    $geometry->ID; // you can also access the data array as properties on the Geometry class

    $geometry->getDataArray(); // methods are passed through to the underlying Shapefile\Geometry\Geometry class
    $geometry->getRaw(); // you can retrieve the underlying Shapefile\Geometry\Geometry class with the getRaw() method
});
...

To-do

We don't currently implement a wrapper around the ShapefileWriter class, since we don't use it. That might be added one day if we need it.

Testing

composer test

The package comes with a small shapefile containing two polygons. Note, we've only tested this with polygons but there's no reason why it shouldn't work with any other kind of feature.
