php - 数组 - foreach 带来 -> fatal error : Cannot use object of type

Question

所以，我对这个阵列很生气，第 2 天让我感到疼痛 *....

我正在开发面向对象的 PHP 脚本。

我得到一个数组:

Array ( [0] => Project Object ( [project_id] => 1 [title] => Some Name [date] => 2011-10-20 [place] => Some City [customer] => 1 [proj_budget] => [manager] => 1 [team] => 1 [currency] => 1 ) )

当我尝试这样做时:

<?php
    $project = new Project();
    $projects = $project->findAll();
    print_r($projects);
    foreach ($projects as $temptwo) {
      echo $temptwo['title'].", \n";
    }
?>

我明白了:

Fatal error: Cannot use object of type Project as array

为什么在世界上？它想从我这里得到什么？

Answer 1

您将项目作为数组访问

echo $temptwo['title'].", \n";

你可能想访问他们的属性

echo $temptwo->title.", \n";
