How to Get the Base Url With PHP

How do I get the base URL with PHP?

Try this:

<?php echo "http://" . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; ?>

Learn more about the $_SERVER predefined variable.

If you plan on using https, you can use this:

function url(){
  return sprintf(
    "%s://%s%s",
    isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http',
    $_SERVER['SERVER_NAME'],
    $_SERVER['REQUEST_URI']
  );
}

echo url();
#=> http://127.0.0.1/foo

Per this answer, please make sure to configure your Apache properly so you can safely depend on SERVER_NAME.

<VirtualHost *>
    ServerName example.com
    UseCanonicalName on
</VirtualHost>

NOTE: If you're depending on the HTTP_HOST key (which contains user input), you still have to make some cleanup, remove spaces, commas, carriage return, etc. Anything that is not a valid character for a domain. Check the PHP builtin parse_url function for an example.

Get base url from string

Use parse_url()

$url = "http://example.com/index.php?data=data&value=value";
$url_info = parse_url($url);
echo $url_info['host'];//hostname

Additionally $user_info contain below

[scheme] => http
[host] => hostname
[user] => username
[pass] => password
[path] => /path
[query] => arg=value
[fragment] => anchor

SO you can get http by scheme

you can do something like :

echo $url_info['scheme'] . '://' . $url_info['host'];//http://example.com

How to get only base url php

Use parse_url from php.net
parse_url

<?php
$url = "https://www.stackoverflow.com/";
echo $domain = parse_url($url, PHP_URL_HOST);
?>
Output: www.stackoverflow.com

<?php
$url = '//www.example.com/path?googleguy=googley';

// Prior to 5.4.7 this would show the path as "//www.example.com/path"
echo "<pre>";
var_dump(parse_url($url));
echo "</pre>";
?>

<?php
echo "<pre>";
var_dump(parse_url($url));
var_dump(parse_url($url, PHP_URL_SCHEME));
var_dump(parse_url($url, PHP_URL_USER));
var_dump(parse_url($url, PHP_URL_PASS));
var_dump(parse_url($url, PHP_URL_HOST));
var_dump(parse_url($url, PHP_URL_PORT));
var_dump(parse_url($url, PHP_URL_PATH));
var_dump(parse_url($url, PHP_URL_QUERY));
var_dump(parse_url($url, PHP_URL_FRAGMENT));
echo "</pre>";
?>

With echo "<pre>"; echo "</pre>"; you can style the output from var_dump, looks better

PHP how to get the base domain/url?

Use SERVER_NAME.

echo $_SERVER['SERVER_NAME']; //Outputs www.example.com

<?php echo base_url();?> and <?php base_url();?>

Please show more about your problem detail like paste your error code in here that we could use those information to help you.

Btw, base_url() isn't a php embedded function, one of the potential problem is that your friend custom a function named base_url() that supposed to return it's root path.
So, you have to either include or build the same function with the same name to your script.

Ex.

function base_url()
{
  return dirname($_SERVER['SCRIPT_FILENAME']);
}

And the 'src' inside your tag should point to your jQuery source file.

how to get the base url in javascript

Base URL in JavaScript

You can access the current url quite easily in JavaScript with window.location

You have access to the segments of that URL via this locations object. For example:

// This article:
// https://stackoverflow.com/questions/21246818/how-to-get-the-base-url-in-javascript

var base_url = window.location.origin;
// "http://stackoverflow.com"

var host = window.location.host;
// stackoverflow.com

var pathArray = window.location.pathname.split( '/' );
// ["", "questions", "21246818", "how-to-get-the-base-url-in-javascript"]

In Chrome Dev Tools, you can simply enter window.location in your console and it will return all of the available properties.
