数组：基于内部数组值的过滤器

Question

过滤这个多维数组以仅获取带有['virtual'] == true的数组的最聪明的方法是什么？？

array (size=3)
  0 => 
    array (size=13)
      'name' => string 'name' (length=4)
      'label' => string 'Nombre' (length=6)
      'sortable' => string 'true' (length=4)
      'property_to_show' => boolean false
      'image' => boolean false
      'virtual' => boolean false  <<<<<<<<<
      'filter_parameter' => boolean false
      'link' => boolean false
      'entity' => boolean false
      'boolean' => boolean false
      'route_parameters' => string 'id' (length=2)
      'text' => string '' (length=0)
      'route' => string '' (length=0)
  1 => 
    array (size=14)
      'virtual' => string 'true' (length=4)  <<<<<<<<<<<
      'label' => string 'Usuarios' (length=8)
      'link' => boolean true
      'class' => string 'DefaultBundle:User' (length=18)
      'entity' => string 'User' (length=4)
      'filter_parameter' => string 'company' (length=7)
      'text' => string 'ver' (length=3)
      'sortable' => boolean false
      'name' => string '' (length=0)
      'property_to_show' => boolean false
      'image' => boolean false
      'boolean' => boolean false
      'route_parameters' => string 'id' (length=2)
      'route' => string '' (length=0)
  2 => 
    array (size=14)
      'virtual' => string 'true' (length=4)  <<<<<<<<
      'label' => string 'Productos exclusivos' (length=20)
      'link' => boolean true
      'class' => string 'DefaultBundle:Product' (length=21)
      'entity' => string 'Product' (length=7)
      'filter_parameter' => string 'company' (length=7)
      'text' => string 'ver' (length=3)
      'sortable' => boolean false
      'name' => string '' (length=0)
      'property_to_show' => boolean false
      'image' => boolean false
      'boolean' => boolean false
      'route_parameters' => string 'id' (length=2)
      'route' => string '' (length=0)

您可以为此使用数组过滤器：

array_filter($array, function($value) {
   return !empty($value['virtual']);
});
