php-PHP如何給這個數組裡增加內容

php數組

$brandData = array(
array('id'=> 1,'value'=> 388, "name"=> "品牌1","type"=>"brand"),
array("id"=> 2,"value"=> 205, "name"=> "品牌2","type"=>"brand"),
array("id"=> 3,"value"=> 215, "name"=> "品牌3","type"=>"brand"),
);
頁面上會傳遞brand的value值
我想根據傳遞過來的值給相應的數組增加下面這個內容
,"selected"=>1

    例如：   array('id'=> 1,'value'=> 388, "name"=> "品牌1","type"=>"brand","selected"=>1),
