指定PHP查询的输出位置
我正在做一个小的PHP项目，作为对该语言的介绍，在格式化数据库查询结果方面遇到了麻烦。我的PHP函数工作正常，但结果显示在所有HMTL之上，如下所示： 这是我的代码，都在一个名为index.php的文件中。有人能指出我哪里出了问题吗？我希望它显示在导航栏（主页、好友列表等）的正下方，如何指定PHP在HTML中的确切显示位置指定PHP查询的输出位置,php,mysql,Php,Mysql,我正在做一个小的PHP项目，作为对该语言的介绍，在格式化数据库查询结果方面遇到了麻烦。我的PHP函数工作正常，但结果显示在所有HMTL之上，如下所示： 这是我的代码，都在一个名为index.php的文件中。有人能指出我哪里出了问题吗？我希望它显示在导航栏（主页、好友列表等）的正下方，如何指定PHP在HTML中的确切显示位置 #!/usr/local/bin/php <!DOCTYPE html> <html lang="en"> <head> &l

颠簸
我相信你想移动这个：
// Load Friend List function
if($_GET['friendList']){friendList();}
要打印好友列表的位置，请执行以下操作：
<div class="container">
<div class="starter-template">
<!-- WE WANT THE FRIENDS LIST HERE -->
<?php
// Load Friend List function
if (isset($_GET['friendList'])) { friendList(); }
?>
</div>
</div><!-- /.container -->
您必须将它添加到
中，我还修改了if
语句，这样，如果好友列表不能设置，它就不会抛出通知。如果（$\u GET['friendList']]{friendList（）；}
也会话启动（）
放置错误。
