Supposons que j'ai un tableau comme celui-ci :

$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", ], ], ];

Je souhaite filtrer ce tableau afin qu'il ne contienne que des détails dont la valeur n'est pas vide. Aircotype值为空，因此它不应返回详细的type. Dans ce cas, le tableau renvoyé devrait ressembler à ceci :

$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", ], ], ];

Je sais que je peux filtrer un tableau en fonction de colonnes vides en utilisant le code suivant (trouvé ici) :

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

Mais comme j'ai un tableau imbriquédetails, je ne sais pas trop comment adapter ce code pour le rendre adapté à mon cas.
