Question

I need a simple function to decide if the it s using https or http. I was thinking - is there a way for php to access the port #? So if it s 443 I know it s secure, and if it s 80 I know it s normal.

有哪些其他方法可以确定这一点?

Answer 1

<?php 
if($_SERVER[ HTTPS ]){ 
  //secure 
}else{ 
  // not secure
} 
?>

然而,有些服务器没有安装HTTPS,在最坏的情况下:

<?php
if (!empty($_SERVER[ HTTPS ]) && $_SERVER[ HTTPS ] !==  off  || $_SERVER[ SERVER_PORT ] == 443) {
  // secure
}
?>
