    if(isset($_SERVER['HTTPS']) && $_SERVER["HTTPS"] == "on"){
        $pageURL .= "s";
    }
    $pageURL .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
        $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $_SERVER["REQUEST_URI"];
    }else{
        $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
    }
    return $pageURL;
}
echo getpageurl();
?>

How to get the url address of the current page without parameters in php

The above two functions about php getting the complete url address of the page will also get the parameters submitted in the url. If we only get an address without parameters, you can refer to the following example!

<?php
function getpageurl_t() {
    $pageURL = 'http';
    if(isset($_SERVER['HTTPS']) && $_SERVER["HTTPS"] == "on"){
        $pageURL .= "s";
    }
    $pageURL .= "://";
    $this_page = $_SERVER["REQUEST_URI"];
    //过滤要提交的参数
    if(strpos($this_page, "?") !== false){
        $this_pages = explode("?", $this_page);
        $this_page = reset($this_pages);
    }
    if ($_SERVER["SERVER_PORT"] != "80") {
        $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $this_page;
    }else{
        $pageURL .= $_SERVER["SERVER_NAME"] . $this_page;
    }
    return $pageURL;
}
?>

<?php
echo getpageurl_t() ;
?>

Other operation methods for obtaining url addresses in php

You can refer to some operation methods on the url address in the following php to realize your own needs!

<?php
//测试网址:   http://localhost/blog/ss.php?id=10
//获取域名或主机地址
echo $_SERVER['HTTP_HOST']."<br>"; // localhost
//获取网页地址
echo $_SERVER['PHP_SELF']."<br>"; // blog/ss.php
 
//获取网址参数
echo $_SERVER["QUERY_STRING"]."<br>"; // id=10
 
//获取用户代理
echo $_SERVER['HTTP_REFERER']."<br>";
 
//获取完整的url
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING'];
// http://localhost/blog/ss.php?id=10
 
//包含端口号的完整url
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
// http://localhost:80/blog/ss.php?id=10
 
//只取路径
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
echo dirname($url);
// http://localhost/blog
?>
