訪問屬性

Question

我得到這個對象：

SimpleXMLElement Object\n(\n  
[@attributes] => Array\n  (\n    
    [article_number] => 550007\n  )\n\n  
[serial_number] => Array\n  (\n    
    [0] => 5500070000126237\n    
    [1] => 5500070000126246\n    
    [2] => 5500070000126255\n    
    [3] => 5500070000126264\n    
    [4] => 5500070000126273\n  )\n\n)\n 

我要訪問這樣的屬性，但它似乎並沒有工作：

foreach ($product_array as $codes) 
{  
    error_log($codes->product[0]->attributes()->article_number);  
} 

Answer 1

$codes->product[0]['article_number'] 

這應該工作。
