PHP如何给数组里增加内容呢？

function addValue($arr，$val)
{
    foreach ($arr as $key=>$value){
        if($value['value']==$val){
              $arr[$key]['selected']=1;
            return $arr;
        }
        return $arr;
    }
}
$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"),
);
$result=addValue($brandData,388);
print_r($result);

试试吧
