问题描述

我是 php 新手，我不知道如何从对象内部的对象获取数据，然后是数组，然后是该数据，所以想从 php 对象获取数据.我用过这个

echo "
";var_dump($res);echo "</pre>";
获取对象数据为:
 object(stdClass)#1 (1) {[1"]=>对象(标准类)#2(13){[childSemCategories"]=>数组(238){[0]=>对象(标准类)#3(13){[childSemCategories"]=>空值[createdById"]=>整数(850)[创建日期"]=>字符串(19)2011-03-14T17:43:50"[显示名称"]=>string(27)磨料和砂轮"[显示名称路径"]=>string(37) "系统 >> 磨料和砂轮"[实体"]=>空值[id"]=>整数(2210)[图像路径"]=>字符串(37)/images/la/s/c/t/n/ctn9mgug_1pe_0.png"[lastModifiedById"]=>整数(850)["lastModifiedDate"]=>字符串(19)2011-11-01T13:39:16"[parentId"]=>整数(1)[parentSemCategory"]=>对象(标准类)#4(13){[childSemCategories"]=>空值[createdById"]=>整数(1)[创建日期"]=>字符串(19)2011-02-16T18:34:48"[显示名称"]=>string(6) "系统"[显示名称路径"]=>string(6) "系统"[实体"]=>空值[id"]=>整数(1)[图像路径"]=>字符串(0)"[lastModifiedById"]=>整数(1)[lastModifiedDate"]=>字符串(19) "2011-07-13T14:10:50"[parentId"]=>空值[parentSemCategory"]=>空值[状态"]=>字符串(6)活动"}[状态"]=>字符串(6)活动"}[1]=>对象(标准类)#5(13){[childSemCategories"]=>空值[createdById"]=>整数(850)[创建日期"]=>字符串(19)2011-03-14T17:46:06"[显示名称"]=>string(25) "丙烯酸塑料和板材"[显示名称路径"]=>string(35) "System >> Acrylic Plastics & Sheets"[实体"]=>空值[id"]=>整数(2242)[图像路径"]=>string(37) "/images/la/s/w/b/n/wbncmgug_1qa_0.png"[lastModifiedById"]=>整数(850)["lastModifiedDate"]=>字符串(19)2011-11-01T13:41:36"[parentId"]=>整数(1)[parentSemCategory"]=>对象(标准类)#6(13){[childSemCategories"]=>空值[createdById"]=>整数(1)[创建日期"]=>字符串(19)2011-02-16T18:34:48"[显示名称"]=>string(6) "系统"[显示名称路径"]=>string(6) "系统"[实体"]=>空值[id"]=>整数(1)[图像路径"]=>字符串(0)"[lastModifiedById"]=>整数(1)["lastModifiedDate"]=>字符串(19) "2011-07-13T14:10:50"[parentId"]=>空值[parentSemCategory"]=>空值[状态"]=>字符串(6)活动"}[状态"]=>字符串(6)活动"}[2]=>对象(标准类)#7(13){[childSemCategories"]=>空值[createdById"]=>整数(2644)[创建日期"]=>字符串(19)2013-01-14T15:30:24"[显示名称"]=>string(19) "粘合剂和填料"[显示名称路径"]=>string(29) "系统 >> 粘合剂和填料"[实体"]=>空值[id"]=>整数(10155)[图像路径"]=>空值[lastModifiedById"]=>整数(2644)[lastModifiedDate"]=>字符串(19)2013-01-14T15:31:01"[parentId"]=>整数(1)[parentSemCategory"]=>对象(标准类)#8(13){[childSemCategories"]=>空值[createdById"]=>整数(1)[创建日期"]=>字符串(19)2011-02-16T18:34:48"[显示名称"]=>string(6) "系统"[显示名称路径"]=>string(6) "系统"[实体"]=>空值[id"]=>整数(1)[图像路径"]=>字符串(0)"[lastModifiedById"]=>整数(1)["lastModifiedDate"]=>字符串(19) "2011-07-13T14:10:50"[parentId"]=>空值[parentSemCategory"]=>空值[状态"]=>字符串(6)活动"}[状态"]=>字符串(6)活动"}[3]=>对象(标准类)#9(13){[childSemCategories"]=>空值[createdById"]=>整数(1)[创建日期"]=>字符串(19)2011-02-16T18:34:48"[显示名称"]=>string(32) "广告、促销和活动"[显示名称路径"]=>string(42) "系统 >> 广告、促销和活动"[实体"]=>空值[id"]=>整数(2)[图像路径"]=>string(35) "/images/la/s/k/0/4/k04dmgug_2_0.png"[lastModifiedById"]=>整数(850)["lastModifiedDate"]=>字符串(19)2011-11-01T13:41:57"[parentId"]=>整数(1)[parentSemCategory"]=>对象(标准类)#10(13){[childSemCategories"]=>空值[createdById"]=>整数(1)[创建日期"]=>字符串(19)2011-02-16T18:34:48"[显示名称"]=>string(6) "系统"[显示名称路径"]=>string(6) "系统"[实体"]=>空值[id"]=>整数(1)[图像路径"]=>字符串(0)"[lastModifiedById"]=>整数(1)["lastModifiedDate"]=>字符串(19) "2011-07-13T14:10:50"[parentId"]=>空值[parentSemCategory"]=>空值[状态"]=>字符串(6)活动"}[状态"]=>字符串(6)活动"}
这里我想获取数据["显示名称"]=>
 解决方案 
使用 get_object_vars() 函数.
$data = get_object_vars($res);//数据包含数组值
你可以循环 $data
foreach($data as $a){if(!is_array($a)) $a = get_object_vars($a);foreach($a 作为 $b){//循环和cek while是对象值}}
I am new on php and i dont know how to get data from object inside object then array and after that data so want to get data from php abject. i have use this 
echo "<pre>";
var_dump($res);
echo "</pre>";

to get objected data as:
 object(stdClass)#1 (1) {
  ["1"]=>
  object(stdClass)#2 (13) {
    ["childSemCategories"]=>
    array(238) {
      [0]=>

      }

Here i am want to get data of
    ["displayName"]=>
 解决方案 
use get_object_vars() function.
$data = get_object_vars($res); // data contain array value

you can looping $data
foreach($data as $a){
   if(!is_array($a)) $a = get_object_vars($a);
   foreach($a as $b){
       //loop and cek while is object value
   }
}
