$map = new MgMap();
$map->Open($resourceService, $mgMapName);
 
$layers = $map->GetLayers();
 
$roadLayer = $layers->GetItem('Roads');

if ($roadLabel == 'Roads')
  $newLabel = 'Streets';
else
  $newLabel = 'Roads';
 
$roadLayer->SetLegendLabel($newLabel);
 
// You must save the updated map or the

$map->Save($resourceService);
