*在确定强调问题后编辑了我的问题.
非常感谢帮助诊断问题的choz *
*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.
***编辑3 ****
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" }
}
解决方法:
Jay,在阅读了所有注释并对您正在使用的模型进行基本搜索之后,您的对象支持toArray()函数,该函数将以没有受保护成员的数组格式返回数据.
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.
