In php, if we want to get the complete url address of the current page, we need to use several common php global variable functions, mainly using the variables $_SERVER[]. Let me show you how to get the complete url address of the current page. Program it.

Let’s take a look at some first

$_SERVER[ 'SERVER_NAME' ] #The name of the server host where the script is currently running.
$_SERVER[ 'QUERY_STRING' ] #Query string.
$_SERVER[ 'HTTP_HOST' ] #Contents of the Host: header of the current request.
$_SERVER[ 'HTTP_REFERER' ] #The URL address of the previous page linked to the current page.
$_SERVER[ 'SERVER_PORT' ] #Port used by the server
$_SERVER[ 'REQUEST_URI' ] #The URI required to access this page.

With some surface functions we can start

Let’s first look at some base methods

Two methods of baseUrl

Method 1:

The code is as follows

Copy code

代码如下	复制代码
// 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; }

// baseUrl

function baseUrl($uri=''){
$baseUrl = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') ? 'https://' : 'http://';

$baseUrl .= isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : getenv('HTTP_HOST');

代码如下

复制代码

    /**
     * Suppose, you are 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']."/";
    }

$baseUrl .= isset($_SERVER['SCRIPT_NAME']) ? dirname($_SERVER['SCRIPT_NAME']) : dirname(getenv('SCRIPT_NAME'));

return $baseUrl.'/'.$uri;

}

代码如下	复制代码
/** @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(); ?>

Method 2:

The code is as follows

Copy code

/** * Suppose, you are 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 3

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();<🎜> ?>
