我花了几周时间尝试修复我的PHP代码。我需要一些指导
我的代码假设要显示多部电影。但是，它只显示一部电影。我知道我想告诉你我的尝试。我已经移动了代码，检查了数据库，但没有任何改变。用于工作的代码，但我添加了一些新代码，代码现在无法正常工作。然后我删除了新代码，但问题仍在继续。我有一个很多的代码，并意识到这个问题将被删除。 这就是我要问的：如果你看到一些奇怪的东西，请对它进行评论。
注意：我保证db信息没有背景，并且db中有多行信息。谢谢！

更新
有一点需要注意的是，ONE电影来自数据库中最后一行的结果，而不是数据库中的第一行。通常，如果while循环出现问题，则信息仅来自FIRST数据库。如果ONE电影来自数据库中的最后一行，这意味着什么？我正在尝试提供更多信息，以便用户更好地了解如何解决此问题...

1 个答案:
答案 0 :(得分：1)
这些是一些需要改进的地方
-
总是把session_start（）作为代码中的第一件事，后面的那些包括会使用会话而你的代码会失败 - Muhammed M.刚刚编辑
-
$name = $_GET["name"]; $name2 = $_GET["name2"];确保它们已设置，如下所示替换：$name=isset($_GET['name'])? $_GET['name']:'';如果设置了$ _GET [＆＃39; name＆＃39;]，您将以$ name命名，否则$ name将为空字符串＆＃39;＆＃39;。对所有$ _GET，$ _POST或任何其他变量执行此操作只是假设它就在那里，而实际上它可能不存在。 -
尝试更难从PHP中分离HTML。至少你可以做的就是把所有与PHP相关的代码放在首位，即使它的代码是＆＃39; foreach构造你的表，将它分配给一个变量，并包含在你的html中。最好有两个文件：
main.php，main_html.php，你得到它，就像这样。 -
你在echo（）之后有header（），它不会工作，会给出错误。必须在任何输出之前调用
header()。将您的所有if(..) { header()}移至页面顶部。该重定向逻辑应该是代码中的第一个。
还有其他一些事情，但我觉得这些对你来说至关重要。
还有一件事 - 请查看其他代码，了解如何正确编码，并且您会喜欢PHP。不要看一些垃圾代码并指责PHP。下载众所周知的PHP框架，挖掘内部了解PSR-0，PSR-1等等。这些都将帮助您成为更好的程序员。是的 - 不要放弃！许多年的PHP背后，但我仍然每天都在学习））
