I'm using $_SERVER["PATH_INFO"] to pass values to the backend through the url, other than ?chave=valor , instead, /:valor/ (I identify the colon and return a variable with that name) when I have a request for url //valor/ the value of $_SERVER["PATH_INFO"] is /valor/ , causing some problems ...
Why? And how to solve?
I solved the problem using $_SERVER["SCRIPT_NAME"] and $_SERVER["REQUEST_URI"] :
//Requisição para example.com/index.php/foo//bar/baz
$current_route = str_replace("/", "\/", $_SERVER["SCRIPT_NAME"]); // \/index.php"
$current_route = preg_replace("/(\.[a-z]*)/", "($1)?", $current_route); // \/index(.php)?
$current_route = preg_replace("/{$current_route}/", "", $_SERVER["REQUEST_URI"]); // /foo//bar/baz
The second line makes optional the .php extension because I hid it by .htaccess
