Intl PHP module in Wamp

Question

Took out an app from my linux system and set it up on Wamp right now. The app loads the Intl module from PHP, but the locale class doesn't work. The SO settings are all right. Debbuging

$get_locale = locale_accept_from_http($_SERVER['HTTP_ACCEPT_LANGUAGE']);
var_dump($get_locale);
setlocale(LC_ALL, $get_locale);
$locale_info = localeconv();
var_dump($locale_info);

I got:

 C:\wamp64\www\mysite\index.php:8:
array (size=18)
  'decimal_point' => string '.' (length=1)
  'thousands_sep' => string '' (length=0)
  'int_curr_symbol' => string '' (length=0)
  'currency_symbol' => string '' (length=0)
  'mon_decimal_point' => string '' (length=0)
  'mon_thousands_sep' => string '' (length=0)
  'positive_sign' => string '' (length=0)
  'negative_sign' => string '' (length=0)
  'int_frac_digits' => int 127
  'frac_digits' => int 127
  'p_cs_precedes' => int 127
  'p_sep_by_space' => int 127
  'n_cs_precedes' => int 127
  'n_sep_by_space' => int 127
  'p_sign_posn' => int 127
  'n_sign_posn' => int 127
  'grouping' =>
    array (size=0)
      empty
  'mon_grouping' =>
    array (size=0)
      empty 

In addition, the Wamp reports a Warning:

Warning: There is Wampserver path (c:/wamp64) into Windows PATH environnement variable: (C:\wamp64\bin\php\php8.2.0) Warning: It seems that a PHP installation is declared in the environment variable PATH C:\wamp64\bin\php\php8.2.0 Wampserver does not use, modify or require the PATH environment variable. Using a PATH on Wampserver or PHP version may be detrimental to the proper functioning of Wampserver.

...but there are not envvars in the path.

Any insights are well come.

To get the locale information, but i got an empty array.
