[PORTE Loïc]

When I install the package php-ps the decimal point of my php change.
Exemple :
before the installation

php > print_r(localeconv());
Array
(
    [decimal_point] => .
    [thousands_sep] =>
    [int_curr_symbol] =>
    [currency_symbol] =>
    [mon_decimal_point] =>
    [mon_thousands_sep] =>
    [positive_sign] =>
    [negative_sign] =>
    [int_frac_digits] => 127
    [frac_digits] => 127
    [p_cs_precedes] => 127
    [p_sep_by_space] => 127
    [n_cs_precedes] => 127
    [n_sep_by_space] => 127
    [p_sign_posn] => 127
    [n_sign_posn] => 127
    [grouping] => Array
        (
