Human Readable Date Using PHP

Question

Please help me create a function to convert dates like

2010-10-04 17:45:50

Into something more pretty like

10 October at 17:45

And so it can hide years if they are not really needed and display date like

today/yesterday at 17:45

This is a bit similar to how Facebook displays past dates.

Try to use this class: I defined some constans to translate to spanish but you can ignore those or make the validation language for the others functions!!

You can focus on the functions: shortDateHuman(), longDateHuman(), shortTimeHuman(), longTimeHuman()

In order to use it you can do: $datetest=new Date($language); and then use

$datetest->longDateHuman();

In addition, you can check the function setGMTOffset if you need it.

class Date {
    var $gmtoffset;
    var $year;
    var $month;
    var $day;
    var $hour;
    var $minute;
    var $second;
    var $idioma;
   function Date($lang) {
        //setlocale (LC_TIME,en_US);
        list($this->year, $this->month, $this->day) = split("-", gmdate("Y-m-d"));
        list($this->hour, $this->minute, $this->second) = split(":", gmdate("g:i:s"));
        $this->gmtoffset = 0;
        $this->idioma=$lang;
    }
    function getYear() {
        return $this->year;
    }
    function setYear($year) {
        $year = intval($year);
        if($year >= 0) {
            $this->year = $year;
        } else {
            //throw new Exception("Invalid year! Prior to 0 A.D.!");
        }
        return true;
    }
    function getMonth() {
        return $this->month;
    }
    function setMonth($month) {
        $month = intval($month);
        if(($month >= 1) && ($month <= 12)) {
            $this->month = $month;
        } else {
            //throw new Exception("Invalid month! Not between 1 and 12!");
        }
        return true;
    }
    function getDay() {
        return $this->day;
    }

            $this->day = $day;
