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

First, the function realization
Example 1:
Copy CodeThe code is 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) {//within 3 days
Return floor ($dur/86400). ' Days ago ';
}else{
return $the _time;
}
}
}

Example 2:
Copy CodeThe code is as follows: function Format_date ($time) {
$t =time ()-$time;
$f =array (
' 31536000 ' = ' year ',
' 2592000 ' + ' months ',
' 604800 ' = ' Week ',
' 86400 ' = ' Day ',
' 3600 ' = ' hours ',
' Five ' and ' minutes ',
' 1 ' = ' s '
);
foreach ($f as $k = = $v) {
if (0! = $c =floor ($t/(int) $k)) {
Return $c. $v. ' Ago ';
}
}
}
?>

Instance 3:
copy code code is 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 the 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) {//within 3 days
Return floor ($dur/86400). ' Days ago ';
}else{
return $the _time;
}
}
}
}
}
}

Second, the realization of the class
Copy the Code Code as follows:/ *
* Author:solon Ring
* time:2011-11-02
* Hair bo Time calculation (year, month, day, hour, minute, second)
* $createtime can be the current time
* $gettime The time you're going 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 ()). "Months 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 the class
/*
*
* 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 ' );
*
