http_build_query没有给出有效的字符串

Question

    $requestParams = [ 'aame_uuid' => 'aba627', 'currency' => 'TEST'];

   ksort($requestParams);

   $hashString = http_build_query($requestParams);

    var_dump( $hashString); 

gives

string(30) "aame_uuid=aba627¤cy=TEST"

so why does currency transformed to ¤cy , how can correct it ?

Answer 1

I think the problem is the &curren html code. http://character-code.com/currency-html-codes.php &curren gets replaced to this char.

Maybe you should add an specific seperator like & to the http_build_query to make sure it will replaced to foo.php?aaaa_uid=aba627&currency=Test
