转到 HTTPS 时 URL 末尾有双斜线？
我的网站目前根据网站上收集的数据使用 http 和 https 部分（表单数据使用 https）。
在我的索引页面上，我的顶部有 PHP 代码：
<?php
session_start();
ob_start();
if( $_SERVER['SERVER_PORT'] == 443) {
header('Location:http://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']));
die();
}
?>
但是，该页面不会加载，并且出现 404 错误。同样，当我使用头代码访问具有 https 安全性的部分时：
<?php
session_start();
ob_start();
if( $_SERVER['SERVER_PORT'] == 80) {
header('Location:https://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']).'/'.basename($_SERVER['PHP_SELF']));
die();
}
?>
该站点没有响应，并且由于某种原因在从 http 切换到 https 时会创建双斜杠。
示例： http://www.abc.com/，然后单击应路由到 enroll.php 的按钮显示 http://www.abc.com//enroll.php
为什么需要双斜杠，有人可以帮助解决 404 错误吗？
My site currently uses http and https sections based on the data being collected on the site (form data uses https).
On my index page, I have the PHP code at the top:
<?php
session_start();
ob_start();
if( $_SERVER['SERVER_PORT'] == 443) {
header('Location:http://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']));
die();
}
?>
However, the page will not load and I get a 404 error. Similarly, when i visit the sections with https security using the head code:
<?php
session_start();
ob_start();
if( $_SERVER['SERVER_PORT'] == 80) {
header('Location:https://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']).'/'.basename($_SERVER['PHP_SELF']));
die();
}
?>
The site does not respond AND for some reason creates a double slash when switching from http to https.
Example: http://www.abc.com/, then clicking button which should route to enroll.php shows http://www.abc.com//enroll.php
why the need for the double slash and can anybody help with the 404 errors?

dirname()不适用于PHP_SELF，因为它不一定是完整目录。dirname("/enroll.php")将正确返回一个空字符串，这又会导致双//。你到底想做什么？
dirname()won't work onPHP_SELFbecause that is not necessarily a full directory.dirname("/enroll.php")will correctly return an empty string, which in turn leads to the double//.What exactly are you trying to do?
