Question

我面临着在数组后检索值的问题。请让我知道我是如何得到的。我想得到第一个价值＆＃39; [_回答]＆＃39;

  WpProQuiz_Model_AnswerTypes Object
  (
   [_answer:protected] => new1
   [_html:protected] => 
   [_points:protected] => 1
   [_correct:protected] => 
   [_sortString:protected] => 
   [_sortStringHtml:protected] =>

   a:4:{i:0;O:27:"WpProQuiz_Model_AnswerTypes":7:  {s:10:"*_answer";s:4:"new1";s:8:"*_html";b:0;s:10:"*_points";i:1;s:11:"*_correct";b:0;s:14:"*_sortString";s:0:"";s:18:"*_sortStringHtml";b:0;s:10:"*_mapper";N;}i:1;O:27:"WpProQuiz_Model_AnswerTypes":7:{s:10:"*_answer";s:4:"new2";s:8:"*_html";b:0;s:10:"*_points";i:1;s:11:"*_correct";b:1;s:14:"*_sortString";s:0:"";s:18:"*_sortStringHtml";b:0;s:10:"*_mapper";N;}i:2;O:27:"WpProQuiz_Model_AnswerTypes":7:{s:10:"*_answer";s:4:"new3";s:8:"*_html";b:0;s:10:"*_points";i:1;s:11:"*_correct";b:0;s:14:"*_sortString";s:0:"";s:18:"*_sortStringHtml";b:0;s:10:"*_mapper";N;}i:3;O:27:"WpProQuiz_Model_AnswerTypes":7:{s:10:"*_answer";s:4:"new4";s:8:"*_html";b:0;s:10:"*_points";i:1;s:11:"*_correct";b:0;s:14:"*_sortString";s:0:"";s:18:"*_sortStringHtml";b:0;s:10:"*_mapper";N;}}

这是一个对象，而不是一个数组。您有两种方法可以访问它的属性。

您可以使用echo WpProQuiz_Model_AnswerTypes->_answer

或者你把它投射到像这样的数组

$asArray = (array)WpProQuiz_Model_AnswerTypes;
echo $asArray['_answer'];
