假设我有一个如下所示的数组：

$array = [ 0 => [ "label" => "Radiator", "details" => 0 => [ "label" => "Condition", "value" => "New", ], 1 => [ "label" => "Type", "value" => "Wall", ], ], 1 => [ "label" => "Airco", "details" => 0 => [ "label" => "Condition", "value" => "New", ], 1 => [ "label" => "Type", "value" => "", ], ], 2 => [ "label" => "Refrigerator", "details" => 0 => [ "label" => "Condition", "value" => "Bad", ], 1 => [ "label" => "Type", "value" => "Wall", ], ], ];

我想过滤这个数组，所以它只包含值不为空的详细信息。 Airco 的type值为空，因此它不应返回详细的type。在这种情况下，返回的数组应如下所示：

$array = [ 0 => [ "label" => "Radiator", "details" => 0 => [ "label" => "Condition", "value" => "New", ], 1 => [ "label" => "Type", "value" => "Wall", ], ], 1 => [ "label" => "Airco", "details" => 0 => [ "label" => "Condition", "value" => "New", ], ], 2 => [ "label" => "Refrigerator", "details" => 0 => [ "label" => "Condition", "value" => "Bad", ], 1 => [ "label" => "Type", "value" => "Wall", ], ], ];

我知道我可以使用以下代码（如此处找到的）基于空列过滤数组：

$result = array_filter($array, function($o) use($column) { return trim( $o[$column] ) !== '' && $o[$column] !== null; });

但是由于我有一个嵌套数组details，我不太确定如何调整此代码以使其适合我的情况。
