我正在尝试从数据库中提取ID以显示在页面标题中，但它不显示它只显示Confession #我需要它像Confession #XX但我无法得到它无论我尝试什么，都要工作。
重新发布，因为我没有得到答案。

$pageTitle = 'Confession '. $row['confessId'].'';是我们正在查看的代码。哦，只是你知道$pageTitle在标题包含文件中，但我没有粘贴在这里，但$ pageTitle确实有效我只需要帮助从数据库中获取ID并在页面标题中显示它像

我认为问题是，当$pageTitle = 'Confession #' . $row['confessId'] . '';运行时，$row['confessId']未设置。
我移动了设置该变量的那部分代码（第177行），并删除了. ''（在这种情况下unusefull）。
