How to get base URL with PHP?

Question

I am using XAMPP on Windows Vista. In my development, I have http://127.0.0.1/test_website/.

How do I get http://127.0.0.1/test_website/ with PHP?

I tried something like these, but none of them worked.

echo dirname(__FILE__)
or
echo basename(__FILE__);
etc.

Answer 1

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.

Answer 2

you can do like this

but sorry my english is not good enough,

first get home base url with this simple code..

i've test this code by local server and public and 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 script, 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,,!

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'];
}

Answer 4

$modifyUrl = parse_url($url);
print_r($modifyUrl)

Its just simple to use
Output :

Array
(
    [scheme] => http
    [host] => aaa.bbb.com
    [path] => /
)

Answer 5

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/

Answer 6

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

http://localhost/directory/subdirectory/something/else
