PHP calculates a few just, several hours ago, a few days ago several functions, class sharing _php instances

One, function realization
Example 1:

Copy Code code as follows:

function Time_tran ($the _time) {
$now _time = Date ("Y-m-d h:i:s", Time () +8*60*60);
$now _time = strtotime ($now _time);
$show _time = strtotime ($the _time);
$dur = $now _time-$show _time;
if ($dur < 0) {
return $the _time;
}else{
if ($dur < 60) {
return $dur. ' seconds ago ';
}else{
if ($dur < 3600) {
Return floor ($dur/60). ' Minutes ago ';
}else{
if ($dur < 86400) {
Return floor ($dur/3600). ' Hours ago ';
}else{
if ($dur < 259200) {//3 days
Return floor ($dur/86400). ' Days ago ';
}else{
return $the _time;
}
}
}

Example 2:

Copy code code as follows:

<?php
function format_date ($time) {
    $t =time ()-$ Time
    $f =array (
        ' 31536000 ' => ' year ',
         ' 2592000 ' => ' month ',
        ' 604800 ' = > ' Week ',
        ' 86400 ' => ' days ',
         ' 3600 ' => ' hours ',
        ' => ' minutes ',
         ' 1 ' => ' sec '
   );
    foreach ($f as $k => $v)     {
        if (0!= $c =floor ($t/(int) $k)) {
            return $c. $ V. ' Before ';
       }
   }
}
?>

Example 3:

Copy Code code as follows:

function Formattime ($date) {
$str = ';
$timer = Strtotime ($date);
$diff = $_server[' Request_time ']-$timer;
$day = Floor ($diff/86400);
$free = $diff% 86400;
if ($day > 0) {
return $day. " Days ago ";
}else{
if ($free >0) {
$hour = Floor ($free/3600);
$free = $free% 3600;
if ($hour >0) {
return $hour. " Hours ago ";
}else{
if ($free >0) {
$min = Floor ($free/60);
$free = $free% 60;
if ($min >0) {
Return $min. " Minutes ago ";
}else{
if ($free >0) {
return $free. " Seconds ago ";
}else{
return ' just ';
}
}
}else{
return ' just ';
}
}
}else{
return ' just ';
}
}
}

Example 4:

Copy Code code as follows:

function Time_tran ($the _time) {
$now _time = Date ("Y-m-d h:i:s", Time () +8*60*60);
$now _time = strtotime ($now _time);
$show _time = strtotime ($the _time);
$dur = $now _time-$show _time;
if ($dur < 0) {
return $the _time;
}else{
if ($dur < 60) {
return $dur. ' seconds ago ';
}else{
if ($dur < 3600) {
Return floor ($dur/60). ' Minutes ago ';
}else{
if ($dur < 86400) {
Return floor ($dur/3600). ' Hours ago ';
}else{
if ($dur < 259200) {//3 days
Return floor ($dur/86400). ' Days ago ';
}else{
return $the _time;
}
}
}
}
}
}

Second, the realization of class

Copy Code code as follows:

<?php
/*
* Author:solon Ring
* time:2011-11-02
* Time calculation (year, month, day, time, minute, second)
* $createtime can be the current time
* $gettime the time you want to pass in
*/

Class mygettime{

function __construct ($createtime, $gettime) {
$this->createtime = $createtime;
$this->gettime = $gettime;
}

function getseconds ()
{
return $this->createtime-$this->gettime;
}

function getminutes ()
{
Return ($this->createtime-$this->gettime)/(60);
}

function GetHours ()
{
Return ($this->createtime-$this->gettime)/(60*60);
}

function Getday ()
{
Return ($this->createtime-$this->gettime)/(60*60*24);
}

function getmonth ()
{
Return ($this->createtime-$this->gettime)/(60*60*24*30);
}

function getyear ()
{
Return ($this->createtime-$this->gettime)/(60*60*24*30*12);
}

Function index ()
{
if ($this->getyear () > 1)
{
if ($this->getyear () > 2)
{
Return date ("y-m-d", $this->gettime);
Exit ();
}
Return Intval ($this->getyear ()). "Years ago";
Exit ();
}

if ($this->getmonth () > 1)
{
Return Intval ($this->getmonth ()). "Month ago";
Exit ();
}

if ($this->getday () > 1)
{
Return Intval ($this->getday ()). "Days Ago";
Exit ();
}

if ($this->gethours () > 1)
{
Return Intval ($this->gethours ()). "Hours ago";
Exit ();
}

             if ($this->getminutes () > 1)
            {
                 return Intval ($this->getminutes ()). "Minutes Ago";
                exit ();
           }

if ($this->getseconds () > 1)
{
Return Intval ($this->getseconds ()-1). "Seconds Ago";
Exit ();
}

}

}
Use instances of classes
/*
*
* Call class Output mode
*
* $a = new Mygettime (Time (), Strtotime (' -25 month '));
* Echo iconv (' Utf-8 ', ' gb2312 ', $a->index ())? Iconv (' Utf-8 ', ' gb2312 ', $a->index ()): Iconv (' utf-8 ', ' gb2312 ', ' current ') );
*
