This is the best method i think so.
$base_url = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != "off") ? "https" : "http");
$base_url .= "://".$_SERVER['HTTP_HOST'];
$base_url .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
echo $base_url;
I had the same question as the OP, but maybe a different requirement. I created this function...
/**
* Get the base URL of the current page. For example, if the current page URL is
* "https://example.com/dir/example.php?whatever" this function will return
* "https://example.com/dir/" .
*
* @return string The base URL of the current page.
*/
function get_base_url() {
$protocol = filter_input(INPUT_SERVER, 'HTTPS');
if (empty($protocol)) {
$protocol = "http";
}
$host = filter_input(INPUT_SERVER, 'HTTP_HOST');
$request_uri_full = filter_input(INPUT_SERVER, 'REQUEST_URI');
$last_slash_pos = strrpos($request_uri_full, "/");
if ($last_slash_pos === FALSE) {
$request_uri_sub = $request_uri_full;
}
else {
$request_uri_sub = substr($request_uri_full, 0, $last_slash_pos + 1);
}
return $protocol . "://" . $host . $request_uri_sub;
}
...which, incidentally, I use to help create absolute URLs that should be used for redirecting.
Here's one I just put together that works for me. It will return an array with 2 elements. The first element is everything before the ? and the second is an array containing all of the query string variables in an associative array.
function disectURL()
{
$arr = array();
$a = explode('?',sprintf(
"%s://%s%s",
isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http',
$_SERVER['SERVER_NAME'],
$_SERVER['REQUEST_URI']
));
$arr['base_url'] = $a[0];
$arr['query_string'] = [];
if(sizeof($a) == 2)
{
$b = explode('&', $a[1]);
$qs = array();
foreach ($b as $c)
{
$d = explode('=', $c);
$qs[$d[0]] = $d[1];
}
$arr['query_string'] = (count($qs)) ? $qs : '';
}
return $arr;
}
Note: This is an expansion of the answer provided by macek above. (Credit where credit is due.)
The following code will reduce the problem to check the protocol. The $_SERVER['APP_URL'] will display the domain name with the protocol
$_SERVER['APP_URL'] will return protocol://domain ( eg:-http://localhost)
$_SERVER['REQUEST_URI'] for remaining parts of the url such as /directory/subdirectory/something/else
$url = $_SERVER['APP_URL'].$_SERVER['REQUEST_URI'];
The output would be like this
$modifyUrl = parse_url($url);
print_r($modifyUrl)
Its just simple to use
Output :
Array
(
[scheme] => http
[host] => aaa.bbb.com
[path] => /
)
$http = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on'? "https://" : "http://";
$url = $http . $_SERVER["SERVER_NAME"] . $_SERVER['REQUEST_URI'];
$some_variable = substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['REQUEST_URI'], "/")+1);
and you get something like
lalala/tralala/something/
function server_url(){
$server ="";
if(isset($_SERVER['SERVER_NAME'])){
$server = sprintf("%s://%s%s", isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http', $_SERVER['SERVER_NAME'], '/');
}
else{
$server = sprintf("%s://%s%s", isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http', $_SERVER['SERVER_ADDR'], '/');
}
print $server;
}
Simple and easy trick:
$host = $_SERVER['HTTP_HOST'];
$host_upper = strtoupper($host);
$path = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
$baseurl = "http://" . $host . $path . "/";
URL looks like this: http://example.com/folder/
$http = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on'? "https://" : "http://";
$dir = str_replace(basename($_SERVER['SCRIPT_NAME']), '',$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME']);
echo $url = $http . $dir;
// echo $url = $http . $_SERVER["SERVER_NAME"] . $_SERVER['REQUEST_URI'];
I think the $_SERVER superglobal has the information you're looking for. It might be something like this:
echo $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']
You can see the relevant PHP documentation here.
I found this on http://webcheatsheet.com/php/get_current_page_url.php
Add the following code to a page:
<?php
function curPageURL() {
$pageURL = 'http';
if ($_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 $pageURL;
}
?>
You can now get the current page URL using the line:
<?php
echo curPageURL();
?>
Sometimes it is needed to get the page name only. The following example shows how to do it:
<?php
function curPageName() {
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}
echo "The current page name is ".curPageName();
?>
$base_url="http://".$_SERVER['SERVER_NAME'].dirname($_SERVER["REQUEST_URI"].'?').'/';
Usage:
print "<script src='{$base_url}js/jquery.min.js'/>";
Fun 'base_url' snippet!
if (!function_exists('base_url')) {
function base_url($atRoot=FALSE, $atCore=FALSE, $parse=FALSE){
if (isset($_SERVER['HTTP_HOST'])) {
$http = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
$hostname = $_SERVER['HTTP_HOST'];
$dir = str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);
$core = preg_split('@/@', str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(dirname(__FILE__))), NULL, PREG_SPLIT_NO_EMPTY);
$core = $core[0];
$tmplt = $atRoot ? ($atCore ? "%s://%s/%s/" : "%s://%s/") : ($atCore ? "%s://%s/%s/" : "%s://%s%s");
$end = $atRoot ? ($atCore ? $core : $hostname) : ($atCore ? $core : $dir);
$base_url = sprintf( $tmplt, $http, $hostname, $end );
}
else $base_url = 'http://localhost/';
if ($parse) {
$base_url = parse_url($base_url);
if (isset($base_url['path'])) if ($base_url['path'] == '/') $base_url['path'] = '';
}
return $base_url;
}
}
Use as simple as:
// url like: http://stackoverflow.com/questions/2820723/how-to-get-base-url-with-php
echo base_url(); // will produce something like: http://stackoverflow.com/questions/2820723/
echo base_url(TRUE); // will produce something like: http://stackoverflow.com/
echo base_url(TRUE, TRUE); || echo base_url(NULL, TRUE); // will produce something like: http://stackoverflow.com/questions/
// and finally
echo base_url(NULL, NULL, TRUE);
// will produce something like:
// array(3) {
// ["scheme"]=>
// string(4) "http"
// ["host"]=>
// string(12) "stackoverflow.com"
// ["path"]=>
// string(35) "/questions/2820723/"
// }
Function adjusted to execute without warnings:
function url(){
if(isset($_SERVER['HTTPS'])){
$protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
}
else{
$protocol = 'http';
}
return $protocol . "://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
}
In my case I needed the base URL similar to the RewriteBasecontained in the .htaccess file.
Unfortunately simply retrieving the RewriteBase from the .htaccess file is impossible with PHP. But it is possible to set an environment variable in the .htaccess file and then retrieve that variable in PHP. Just check these bits of code out:
.htaccess
SetEnv BASE_PATH /
index.php
Now I use this in the base tag of the template (in the head section of the page):
<base href="<?php echo ! empty( getenv( 'BASE_PATH' ) ) ? getenv( 'BASE_PATH' ) : '/'; ?>"/>
So if the variable was not empty, we use it. Otherwise fallback to / as default base path.
Based on the environment the base url will always be correct. I use / as the base url on local and production websites. But /foldername/ for on the staging environment.
They all had their own .htaccess in the first place because the RewriteBase was different. So this solution works for me.
Edited at @user3832931 's answer to include server port..
to form URLs like 'https://localhost:8000/folder/'
$base_url="http://".$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].dirname($_SERVER["REQUEST_URI"].'?').'/';
Try using: $_SERVER['SERVER_NAME'];
I used it to echo the base url of my site to link my css.
<link href="//<?php echo $_SERVER['SERVER_NAME']; ?>/assets/css/your-stylesheet.css" rel="stylesheet" type="text/css">
Hope this helps!
Try the following code :
$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
echo $config['base_url'];
Just test and get the result.
// 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/
echo $protocol.$hostName.$pathInfo['dirname']."/";
Try this. It works for me.
/*url.php file*/
trait URL {
private $url = '';
private $current_url = '';
public $get = '';
function __construct()
{
$this->url = $_SERVER['SERVER_NAME'];
$this->current_url = $_SERVER['REQUEST_URI'];
$clean_server = str_replace('', $this->url, $this->current_url);
$clean_server = explode('/', $clean_server);
$this->get = array('base_url' => "/".$clean_server[1]);
}
}
Use like this:
<?php
/*
Test file
Tested for links:
http://localhost/index.php
http://localhost/
http://localhost/index.php/
http://localhost/url/index.php
http://localhost/url/index.php/
http://localhost/url/ab
http://localhost/url/ab/c
*/
require_once 'sys/url.php';
class Home
{
use URL;
}
$h = new Home();
?>
<a href="<?=$h->get['base_url']?>">Base</a>
You can do it like this, but sorry my english is not good enough.
First, get home base url with this simple code..
I've tested this code on my local server and public and the result is good.
<?php
function home_base_url(){
// first get http protocol if http or https
$base_url = (isset($_SERVER['HTTPS']) &&
$_SERVER['HTTPS']!='off') ? 'https://' : 'http://';
// get default website root directory
$tmpURL = dirname(__FILE__);
// when use dirname(__FILE__) will return value like this "C:\xampp\htdocs\my_website",
//convert value to http url use string replace,
// replace any backslashes to slash in this case use chr value "92"
$tmpURL = str_replace(chr(92),'/',$tmpURL);
// now replace any same string in $tmpURL value to null or ''
// and will return value like /localhost/my_website/ or just /my_website/
$tmpURL = str_replace($_SERVER['DOCUMENT_ROOT'],'',$tmpURL);
// delete any slash character in first and last of value
$tmpURL = ltrim($tmpURL,'/');
$tmpURL = rtrim($tmpURL, '/');
// check again if we find any slash string in value then we can assume its local machine
if (strpos($tmpURL,'/')){
// explode that value and take only first value
$tmpURL = explode('/',$tmpURL);
$tmpURL = $tmpURL[0];
}
// now last steps
// assign protocol in first value
if ($tmpURL !== $_SERVER['HTTP_HOST'])
// if protocol its http then like this
$base_url .= $_SERVER['HTTP_HOST'].'/'.$tmpURL.'/';
else
// else if protocol is https
$base_url .= $tmpURL.'/';
// give return value
return $base_url;
}
?>
// and test it
echo home_base_url();
output will like this :
local machine : http://localhost/my_website/ or https://myhost/my_website
public : http://www.my_website.com/ or https://www.my_website.com/
use home_base_url function at index.php of your website and define it
and then you can use this function to load scripts, css and content via url like
<?php
echo '<script type="text/javascript" src="'.home_base_url().'js/script.js"></script>'."\n";
?>
will create output like this :
<script type="text/javascript" src="http://www.my_website.com/js/script.js"></script>
and if this script works fine,,!
