I replaced the old code snippet with this simple class. This class (my first one, only for testing) is more flexible and can be used for date calculations. You need to translate the week-days and month names in your local language. This is the last release because some simple PHP functions do the same job. class local_date { var $week_day; var $day; var $month; var $year; function local_date() { //constructor $this->week_day = date("l"); $this->day = date("j"); $this->month = date("n"); $this->year = date("Y"); } //translate in local language function get_day() { $nl_day = array("Monday" => "Maandag", "Tuesday" => "Dinsdag", "Wednesday" => "Woensdag", "Thursday" => "Donderdag", "Friday" => "Vrijdag", "Saturday" => "Zaterdag", "Sunday" => "Zondag"); return $nl_day[$this->week_day]; } function get_month() { $nl_month = array("1" => "januari", "februari", "maart", "april", "mei", "juni", "juli", "augustus", "september", "october", "november", "december"); return $nl_month[$this->month]; } function build_date() { $long_date = $this->day."
