Current url multilanguage - php

Question

I have the following code:
public function UrlLang() {
if ( (!isset($_REQUEST['lang'])) || (isset($_REQUEST['lang']) && ($_REQUEST['lang'] == 'es' || $_REQUEST['lang'] == 'ES')) ) {
$Url = SITE_URL .'en/' . array_pop(explode('/', $_SERVER['REQUEST_URI']));
} else {
$Url = SITE_URL .'' . array_pop(explode('/', $_SERVER['REQUEST_URI']));
}
return $Url;
}
The code returns the current url me, the problem is that if my url is not in the root url not work for me.
example:
http: // localhost / My_Cms_Db /
It works well.
http: //localhost/My_Cms_Db/nosotros.php
It works well.
http: //localhost/My_Cms_Db/nosotros/index.php
It does not work well.
Thanks in advance for any help you can give me.

Answer 1

Replace your UrlLang() function with below code and try:
public function UrlLang() {
$Url = str_replace(SITE_URL.'en/',SITE_URL,$_SERVER['REQUEST_URI']);
if(isset($_REQUEST['lang']))
{
$selectedLang = strtolower($_REQUEST['lang']);
if($selectedLang=='es')
{
$Url = str_replace(SITE_URL,SITE_URL.'en/',$_SERVER['REQUEST_URI']);
}
}
return $Url;
}
