Needs better explanation / Read.me #92
Description
Hi, thank you for this awesome tool, it was extremely helpful parsing huge GeoJSON data.
However, the explanation of the really important part is totally missing. It was difficult to find out what's going on. When I went to your blog post the same happened, when I was looking for how to implement the listener the blog post just say: It's pretty straightforward. It is but not for somebody who gets here the first time :)
Here's my code snippet using the GeoJSON Listener for another users who needs a better example:
<?php
ini_set('max_execution_time', 0);
ini_set('memory_limit', -1);
$tmp_file_name = 'geojson.json';
$stream = fopen('/tmp/'.$tmp_file_name, 'r');
$listener = new \JsonStreamingParser\Listener\GeoJsonListener(function($json){
if(!empty($json)){
//var_dump($json['properties']);
////////////////// Do WHATEVER YOU WANT WITH THE FEATURE //////////////////
//Storing in db
$data = [
'title' => !empty($json['properties']['shapeName']) ? $json['properties']['shapeName'] :$json['properties']['shapeISO'],
'iso' => $json['properties']['shapeISO'],
'gb_id' => $json['properties']['shapeID'],
'country_iso' => $json['properties']['shapeGroup'],
'admin_level' => str_replace('ADM', '', $json['properties']['shapeType']),
];
$json['properties'] = $data;
$data['geometry'] = json_encode($json);
try{
//Mock DB insert
DB::table('geoboundaries')->insert($data);
}catch (\Exception $exception){
dd(substr($exception->getMessage(), 0, 300));
}
}
});
try {
$parser = new \JsonStreamingParser\Parser($stream, $listener);
$parser->parse();
fclose($stream);
return true;
} catch (Exception $e) {
fclose($stream);
throw $e;
}
