如何解析PHP stdObject

Question

Hello There I have the following code:

stdClass Object ( 
  [num_rows] => 3 [row] => Array ( 
     [product_id] => 2439 [author_id] => 39 [author_attribute_id] => 0 
   ) [rows] => Array ( 
     [0] => Array ( 
       [product_id] => 2439 [author_id] =>  39 [author_attribute_id] => 0 ) 
     [1] => Array ( 
       [product_id] => 2439 [author_id] => 156 [author_attribute_id] => 0 ) 
     [2] => Array ( 
       [product_id] => 2439 [author_id] => 684 [author_attribute_id] => 0 )
    ) 
 ) 

now I'd like to extract the author_id values. How do I do this?

Answer 1

You might want to access properties do it like that:

$obj->property

Or if you don't often use object you might find this function useful:

function objectToArray($obj)
{
    if (is_object($obj))
        $obj = get_object_vars($obj);
    if (is_array($obj))
        return array_map(__CLASS__.'::'.__FUNCTION__, $obj);
    else
        return $obj;
}

It converts an Object to an Array.

Answer 2

例如： $obj->$row->author_id

Answer 3

first of all thanks for all your answers Solved my problem with the following code

 for($i=0;$i<obj->num_rows;$i++)    {
    $array = obj->rows[i];
    echo $array['author_id'];
    }

Well thanks again for posting your answers......and sorry for late reply......

Answer 4

$object->row->author_id

foreach ($object->rows as $row) {
    echo $row->author_id;
}
