Is there are a way to get base url (url_helper in codeigniter) like codeigniter using only php.
My project address looks like
http://localhost/proj1/
and it can be any name
how to get the URL which will give the same base URL on any file in the structure tree, depending on all situations like http:// or https://
Setup a file config.php
<?php
define('base_url','http://localhost/proj1/');
?>
On every page include config.php. Like this :
page1.php
<?php
include_once('config.php');
echo base_url;
?>
For more info about define(); read this
Edit 1 :
if you want you can try this also :
<?php
define('base_url','http://'.$_SERVER['HTTP_HOST'].'/');
?>
Or if your using sub folder then :
$root = "http://".$_SERVER['HTTP_HOST'];
$root .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
define('base_url',$root);
Edit 2 : Try this one :
define('ROOTPATH', realpath(dirname(__FILE__)) . '/');
// installed in the docroot?
if (realpath(dirname(__FILE__)) == $_SERVER['DOCUMENT_ROOT'])
{
define('ROOT', '/');
}
else
{
define('ROOT', substr(ROOTPATH, strlen($_SERVER['DOCUMENT_ROOT'])+1));
}
$url = (isset($_SERVER['HTTPS']) ? "https://" : "http://") . $_SERVER['HTTP_HOST'] . ROOT;
define('base_url',$url);
echo base_url;exit;
base_url on every page so if you change the URL in config.php file it will effect on every pageOr if you want it in php and not codeigniter try the $_SERVER variables of php
echo "http://" . $_SERVER['SERVER_NAME'];
This is how codeigniter does it, straight from the git repository:
https://github.com/EllisLab/CodeIgniter
CodeIgniter / application / config / config.php
/*
|--------------------------------------------------------------------------
| Base Site URL
|--------------------------------------------------------------------------
|
| URL to your CodeIgniter root. Typically this will be your base URL,
| WITH a trailing slash:
|
| http://example.com/
|
| If this is not set then CodeIgniter will guess the protocol, domain and
| path to your installation.
|
*/
$config['base_url'] = '';
CodeIgniter / system / core / Config.php
/**
* Class constructor
*
* Sets the $config data from the primary config.php file as a class variable.
*
* @return void
*/
public function __construct()
{
$this->config =& get_config();
log_message('debug', 'Config Class Initialized');
// Set the base_url automatically if none was provided
if (empty($this->config['base_url']))
{
if (isset($_SERVER['HTTP_HOST']))
{
$base_url = (is_https() ? 'https' : 'http')
.'://'.$_SERVER['HTTP_HOST']
.substr($_SERVER['SCRIPT_NAME'], 0, -strlen(basename($_SERVER['SCRIPT_NAME'])));
}
else
{
$base_url = 'http://localhost/';
}
$this->set_item('base_url', $base_url);
}
}
You should provide a base url in the config file, I presume this will then get autoloaded by codeigniter and the base_url() will return this value.
Whenever config.php gets instantiated it checks to see if the base url has been configured in the config.php, if it hasn't it will try and guess by checking the host, protocol base name of the script etc. Then the set_item method is called, which would set $config['base_url'] to whatever the logic above has determined to be the base url
