I developed a PHP shopping cart for a website that has world wide sales. Because of it's international traffic, I'm using setlocale() and localeconv() to display 'USD' next to all prices whenever the locale is not en_US. This works great when my code is hosted at places like Hostgator, Westhost, even GoDaddy, but it's not working on my DigitalOcean "Droplet". Here's what I get from localeconv() from Hostgator: $locale_info => Array (18) ( | ['decimal_point'] = String(1) "." | ['thousands_sep'] = String(0) "" | ['int_curr_symbol'] = String(4) "USD " | ['currency_symbol'] = String(1) "$" | ['mon_decimal_point'] = String(1) "." | ['mon_thousands_sep'] = String(1) "," | ['positive_sign'] = String(0) "" | ['negative_sign'] = String(1) "-" | ['int_frac_digits'] = Integer(1) 2 | ['frac_digits'] = Integer(1) 2 | ['p_cs_precedes'] = Integer(1) 1 | ['p_sep_by_space'] = Integer(1) 0 | ['n_cs_precedes'] = Integer(1) 1 | ['n_sep_by_space'] = Integer(1) 0 | ['p_sign_posn'] = Integer(1) 1 | ['n_sign_posn'] = Integer(1) 1 | ['grouping'] => Array (0) | ( | ) | ['mon_grouping'] => Array (2) | ( | | ['0'] = Integer(1) 3 | | ['1'] = Integer(1) 3 | ) ) And here's what it looks like on Disital Ocean: $locale_info => Array (18) ( | ['decimal_point'] = String(1) "." | ['thousands_sep'] = String(0) "" | ['int_curr_symbol'] = String(0) "" | ['currency_symbol'] = String(0) "" | ['mon_decimal_point'] = String(0) "" | ['mon_thousands_sep'] = String(0) "" | ['positive_sign'] = String(0) "" | ['negative_sign'] = String(0) "" | ['int_frac_digits'] = Integer(3) 127 | ['frac_digits'] = Integer(3) 127 | ['p_cs_precedes'] = Integer(3) 127 | ['p_sep_by_space'] = Integer(3) 127 | ['n_cs_precedes'] = Integer(3) 127 | ['n_sep_by_space'] = Integer(3) 127 | ['p_sign_posn'] = Integer(3) 127 | ['n_sign_posn'] = Integer(3) 127 | ['grouping'] => Array (0) | ( | ) | ['mon_grouping'] => Array (0) | ( | ) ) I'm guessing there is something that I need to install/setup. Anybody know what? I'm running LAMP on Ubuntu 12.04
