Greetings to all I am working on a system in PHP, and I would like to know if there is a function that makes PHP recognize or use the currency that is defined in windows!

php

  • In windows? Wouldn’t it be better defined by the browser?

  • How would you define it so

  • How so currency defined in Windows? Does it refer to detect the person’s country and configure the currency exchange and type? I could explain better what you need so we can guide you?

When your browser requests a web page, it sends a language acceptance header ACCEPT_LANGUAGE that tells you which languages you can accept the content and in what order.

Examples of strings returned by header HTTP_ACCEPT_LANGUAGE

  • es-ES,es;q=0.8,en-US;q=0.5,en;q=0.3
  • en-US,en;q=0.8,pt-BR;q=0.6,pt;q=0.4

Mine on this machine is:

  • pt-BR,pt;q=0.8,en-US;q=0.6,en;q=0.4

that is to say, I prefer the Brazilian Portuguese, if it doesn’t have it can be "general" Portuguese (weight 0.8). In the absence of these, I can accept US English (q = 0.6), and finally "general" English (weight 0.4)

The parameter q (quality factor), indicates user preference order.

With this string we can make PHP use the currency based on this information. 

/*idioma do navegador do Usuário (o primeiro da lista que tem a mais alta preferencia 
e tem formatação próxima a necessária para uso em setlocale).
entre as aspas simples pode colocar uma default (exemplo: pt-BR ou en-US)
*/
$http_lang = isset($_SERVER["HTTP_ACCEPT_LANGUAGE"]) ? substr($_SERVER["HTTP_ACCEPT_LANGUAGE"],0,5) : '';

//formata para valor válido em setlocale
//substitui o "-" (tracinho) por "_" (underline)
$http_lang = str_replace("-","_",$http_lang);

//Define informações locais
setlocale(LC_ALL, $http_lang);

//retorna dados baseados na localidade corrente definida por setlocale().
$locale_info = localeconv();

//Simbolo da moeda local
$simbolo = $locale_info['currency_symbol'];
//caractere decimal
$decimal_point = $locale_info['decimal_point'];
//Separador de Milhares 
$thousands = $locale_info['thousands_sep'];

Example of use:

$valor = 12345678900;

echo $simbolo.number_format($valor,2,$decimal_point,$thousands);

see result in ideone

Most browsers have settings that allow you to check or change language preference settings.
