PHP get the current page full URL address instance _php tutorial

In PHP we want to get the current page full URL address need to use a few common PHP global variables function, mainly with $_server[] These variables, I will show you a get the current page full URL address program bar.

First look at some

$_server[' server_name '] #当前运行脚本所在服务器主机的名称.
A string of $_server[' query_string '] #查询 (QUERY).
$_server[' Http_host '] #当前请求的 HOST: The contents of the head.
$_server[' Http_referer '] #链接到当前页面的前一页面的 URL address.
$_server[' Server_port '] #服务器所使用的端口
$_server[' Request_uri '] #访问此页面所需的 URI.

With some polygon functions, we can start.

First look at some base methods

Two ways of BaseURL

Method One:

The code is as follows	Copy Code
BaseUrl function BaseUrl ($uri = ") { $BASEURL = (isset ($_server[' https "]) && $_server[' https ']! = ' off ')? ' https://': '/HTTP '; $baseUrl. = Isset ($_server[' http_host ')? $_server[' http_host ': getenv (' http_host '); $baseUrl. = Isset ($_server[' script_name ')? DirName ($_server[' script_name '): DirName (getenv (' script_name ')); return $BASEURL. ' /'. $uri; }

Method Two:

code as follows

copy code

/** * Suppose, browsing in your localhost * Http://localhost/myproject/index.php?id=8 */ function BaseUrl () { Output:/myproject/index.php $currentPath = $_server[' php_self '); Output:array ([dirname] =/myproject [basename] = index.php [extension] = php [filename] + index) $pathInfo = PathInfo ($currentPath); Output:localhost $hostName = $_server[' http_host '); output:http:// $protocol = Strtolower (substr ($_server["Server_protocol"],0,5)) = = ' https://'? ' https://': '/HTTP '; return:http://localhost/myproject/ Return $protocol. $hostName. $pathInfo [' dirname ']. " /"; }

Method Three

The code is as follows

Copy Code

/** * @author McKee * @blog http://www.bKjia.c0m */ function Get_page_url () { $url = (isset ($_server[' Server_port ')) && $_server[' server_port '] = = ' 443 ')? ' https://': '/HTTP '; $url. = $_server[' http_host '); $url. = Isset ($_server[' Request_uri ')? $_server[' Request_uri ': UrlEncode ($_server[' php_self ']). '?' . UrlEncode ($_server[' query_string '); return $url; } Echo Get_page_url (); ?>

Here's how to get the full path to the current page:

code as follows

copy code

< p>!--? php function getfullurl () { # fix common problem $requestUri = '; if (Isset ($_server[' Request_uri ']) { #$_server["Request_uri"] only Apache support, $requestUri = $_server[' Request_uri '); } else { if (isset ($_server[' A RGV ']) { $requestUri = $_server[' php_self ']. '? '. $_server[' argv '][0]; } else if (Isset ($_server[' query_string ') ]) { $requestUri = $_server[' php_self ']. '? '. $_server[' query_string ']; } } //echo $requestUri. ' '; $scheme = Empty ($_server["HTTPS"])? ": ($_server[" HTTPS "] = =" on ")? "s": ""; $protocol = strstr (Strtolower ($_server["Server_protocol"]), "/", true). $scheme; $port = ($_server["Server_port"] = = "80")? "": (":". $_server["Server_port"]); # Gets the full URL $_fullurl = $protocol. "://" . $_server[' server_name '. $port. $requestUri; return $_fullurl; }

Echo Getfullurl (); Note: PHP does not have built-in functions. We need to combine the parameters on the URL to implement the entire URL
