Usage

• For GeoJsonSql
  • process_and_save() Returns the $polygon array formatted for inclusion in a query. Also accepts a PDO statement if you want to save in a database.
  • process_with_query(PDO $db,$table,$name) Creates a PDO query with a single value which is replaced with the polygon
• For SqlGeo
  • search_json(Array $where) Returns a JSON string based on the submitted query e.g. ['item_id' => 25]

Example

For GeoJsonSql:

require __DIR__.'/vendor/autoload.php';

$db=new PDO('mysql:host=localhost;dbname=database','user','pass');

$file_name='geojson.json';

$geojson = new GeoJsonSql($file_name);
$geojson->process_with_query($db,'table','polygon_field');

For SqlGeo:

require __DIR__.'/vendor/autoload.php';

$db=new PDO('mysql:host=localhost;dbname=geospatial','root','');

$sqljson=new SqlGeo($db,'table','polygon_field');
echo $sqljson->search_json(['title'=>'Polygon Title']);
