我想用foreach循環

由於即時通訊新到它，我第一次開始打印SKU，名稱，價格的價值打印單個值

echo $data->items->arr[0]->sku; 
Notice: Trying to get property of non-object getting this error 

但我想打印在foreach中的值請幫助！

Answer 1

項目是主要對象的屬性，本身就是一個數組。這就是你追求的：

foreach($data->items as $d) { 
    echo $d->name, '<br />', $d->sku, '<br />', $d->price; 
} 

如果要訪問這些元素的一個無環路，您需要提供數組的索引，例如：

echo $data->items[0]->name 

Answer 2

爲您簡單的方法是轉換對象數組

function array2object($array) { 

    if (is_array($array)) { 
     $obj = new StdClass(); 

     foreach ($array as $key => $val){ 
      $obj->$key = $val; 
     } 
    } 
    else { $obj = $array; } 

    return $obj; 
} 

function object2array($object) { 
    if (is_object($object)) { 
     foreach ($object as $key => $value) { 
      $array[$key] = $value; 
     } 
    } 
    else { 
     $array = $object; 
    } 
    return $array; 
} 


// example: 

$array = array('foo' => 'bar', 'one' => 'two', 'three' => 'four'); 

$obj = array2object($array); 

print $obj->one; // output's "two" 

$arr = object2array($obj); 

print $arr['foo']; // output's bar 

Answer 3

foreach($data['items'] as $item) { 

    echo $item['sku'].PHP_EOL 
    echo $item['name'].PHP_EOL 
    echo $item['price'].PHP_EOL; 

}
