How To Parse a 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?

OK. Have you tried anything at all? Have you looked at the manual for PHP classes/arrays? — h2ooooooo

When you say you want to "parse" it, do you mean you have that as a string of text, and want to turn it back into an object? Or just that you have an object (which looks like that when displayed with var_dump or print_r), and don't know how objects work in PHP? — IMSoP

@IMSoP I think he's got an object and doesn't know how to access properties — Adam Sinclair

@AdamSinclair That would be my guess too, but I was hoping the OP would clarify for themselves. — IMSoP

For your example: $obj->$row->author_id

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.

$object->row->author_id

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

Thanks for one of your first posts. You might want to look at syntax highlighting and add some comment to your code.
