脚本宝典收集整理的这篇文章主要介绍了php – 将Object的受保护成员的数据复制到数组中的最佳方法,脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
*描述*
我有一个有两个成员的班级,相应地保存专辑数据和照片数据.
在构造函数中,我使用从DB查询中提取的数据填充它们.
这些查询返回一个Object,该数组是Object的受保护成员.
我试图在Object中添加一个新的键和值,并将一个关联数组错误地视为一个数组.
这些新的关键和价值没有设定.大概是因为Object的数组成员受到保护.
请参阅下面的VAR dump,其中Object转储的开头位置为:
[ “数据”:保护].
这是问题吗?如果是这样,创建我自己可以自由操作的副本的最佳方法是什么?
/****** Class Memebers ********/ //Object wITh array of associative album arrays. //each inner album array is defined by unique key ='albumID'. PRivate $member_albums; //array of objects holding associative photo arrays. //Each inner photo array is defined by unique key ='albumID'. private $member_photos;
/* * For each photo in each album,we will add a new key and value. * key = 'img_url',value is an array with structure of * ['S']['{url pointing to this photo in storage}'] where 'S' is the * key (representing a string value) and value is the url string. */ private function add_Photo_Url_To_Photos_Data_Array(){ // If data was retrieved From DB without errors // because query fail returns false. if( $this->member_albums && $this->member_photos){ // If user has albums - because 'Count' is always 0 or // greater,representing the number of inner arrays if($this->member_albums['Count'] > 0 ){ // For number of albums foreach ($this->member_albums['Items'] as $albumArr) { // current album ID $curr_AlbumId = $albumArr['albumID']['S']; // If current album contains photos if( $this->member_photos[$curr_AlbumId]['Count'] > 0){ // For each photo in this album foreach( $this->member_photos[$curr_AlbumId]['Items'] as &$photosArr) { // method that creates a url from photo data- returns string url $url = $this->build_Photo_Url($photosArr,$curr_AlbumId); // Insert new key = 'img_url' and value into the array. // new value is itself an array with key ['S'] // signifying a string and value $url $photosArr['img_url'] = array('S' => $url); // this echo shows key and value were added // correctly into $photosArr echo ' <br>Img URL = ' . $photosArr['img_url']['S']; } } } } }
但是如果我尝试从$this-> member_photos数组项回显’img_url’,它就不存在了.
谢谢.

添加var_dump($this-> member_albums)和var_dump($this-> member_photos)
的var_dump($这 – > member_albums)
object(Guzzle\Service\Resource\Model)#88 (2) { ["structure":protected]=> NULL ["data":protected]=> array(3) { ["Count"]=> int(2) ["Items"]=> array(2) { [0]=> array(7) { ["PlaceLong"]=> array(1) { ["N"]=> string(1) "0" } ["AlbumId"]=> array(1) { ["S"]=> string(7) "album_1" } ["Title"]=> array(1) { ["S"]=> string(5) "test1" } ["UserId"]=> array(1) { ["S"]=> string(36) "810725E5-D235-43F7-AA50-4CCDACD6AB36" } ["Year"]=> array(1) { ["N"]=> string(1) "0" } ["PlaceLat"]=> array(1) { ["N"]=> string(1) "0" } ["Timestamp"]=> array(1) { ["N"]=> string(16) "472572846.470462" } }
的var_dump($这 – > member_photos)
array(2) { ["album_1"]=> object(Guzzle\Service\Resource\Model)#89 (2) { ["structure":protected]=> NULL ["data":protected]=> array(3) { ["Count"]=> int(5) ["Items"]=> array(5) { [0]=> array(8) { ["ShotId"]=> array(1) { ["S"]=> string(6) "Photo2" } ["AlbumId"]=> array(1) { ["S"]=> string(7) "album_1" } ["UserId"]=> array(1) { ["S"]=> string(16) "1111-11111-11111" } ["Year"]=> array(1) { ["N"]=> string(1) "0" } ["Discovery"]=> array(1) { ["N"]=> string(1) "0" } ["Timpstamp"]=> array(1) { ["N"]=> string(14) "472572840.3845" } ["ExtractedPhotoId"]=> array(1) { ["S"]=> string(32) "Photo2_0-0-746-0-0-1000-746-1000" } ["ManualEdit"]=> array(1) { ["N"]=> string(1) "0" } }
这是参考:http://docs.aws.amazon.com/aws-sdk-php/v2/guide/feature-models.html
首先,尝试运行var_dump(get_class_methods($this-> member_albums)));看看它将返回什么样的方法.我确信有一个内置的toArray()函数,主要是因为它是一个响应,所以它们可以让你轻松提取和操作你的数据.
首先尝试var_dump(),然后尝试执行以下$clearArr = $this-> member_albums-> toArray();和print_r / var_dump $clearArr,它应该导致标准的多维数组.
