Easily transform arrays and objects with different layouts into one format. Think importing data from several sources in different formats to generate statistics or exports.

Usage

$ composer require coderofsalvation/datamapper-minimal

And then

<? 
  use coderofsalvation\DataMapper;
  $datamapper = new DataMapper();
?> 

Lets say this is our desired object format:

class MyObject {
  public $name;
  public $id;
}

But source A provide these object formats:

[{ "short_name": "foo", "ID": 12 },{ "short_name": "bar", "ID":13}]

And oh no! source B has this object format:

<items> 
  <item id="15">
    <Name>Boo</Name>
  </item>
</items>       

This is going to be a mess...or not? Nope, we can just define transformations and convert them in batch:

$datamapper->addMapping("A", array(
  array( "source" => "short_name", "destination" => "name", "transform" => function($s,&$d){ return $s->short_name;    } ), 
  array( "source" => "id",         "destination" => "id",   "transform" => function($s,&$d){ return $s->id;            } ) 
));

$datamapper->addMapping("B", array(
  array( "source" => "Name", "destination" => "name",       "transform" => function($s,&$d){ return $s->Name;                } ), 
  array( "source" => "Id",   "destination" => "id",         "transform" => function($s,&$d){ return $s->getAttribute("id");  } )
));

// lets do it!
$items = [];
foreach( $Aitems as $item ) $items[] = $datamapper->map("A", $item, new MyObject() );
foreach( $Bitems as $item ) $items[] = $datamapper->map("B", $item, new MyObject() );

print_r($items);
// voila there you go :D
